Phase Change Lesson 3.5: Warm-Up Share-Out [Blue Group] by Theodore Stocking

tnstocking — 2020-12-08 14:14:32 UTC

Why do you think that the office worker's can of soda was covered in a thin layer of liquid? Where did the liquid come from?

hmatya653 — 2020-12-11 16:14:53 UTC

the water was condensation. Condensation happens when gas sticks to a clod surface. The coolness of the can made the gas turn into a liquid.

kelanchezhiyan758 — 2020-12-11 16:15:29 UTC

The kind of liquid that is so on the office worker's soda can is a liquid. The liquid evaporated and escaped the can and it condensed on the can/bottle and it made water droplets. I think this because if it didn't evaporate and condense, there wouldn't be water on the outside.

what kawin said

kwaskiewicz281 — 2020-12-11 16:15:58 UTC

i think that the kind of liquid is water and the water is changing phase. I think that the water is condensing or going from a gas to a liquid and that is where the droplets come from. The water from the air in a gas form turns into a liquid

akurz622 — 2020-12-11 16:16:07 UTC

I think that energy was transferred to the can from the air. This means the air molecules lost kinetic energy, and now the molecular attraction is stronger than the amount of energy. This caused the water molecules to condense and change phase into a liquid. The droplets on the outside of the can is water.

ltigeris334 — 2020-12-11 16:16:28 UTC

The liquid on the can is water because it came from the water vapor in the air. This phase change is known as condensation. It is when a can of soda is cooler than the atmosphere so the water goes onto the can condensing turning it into a because energy been taken out of it.

pengstrom691 — 2020-12-11 16:18:15 UTC

Condensation happened because it was cold, and when the cold drink mixed with the warm air and it formed droplets on the side of the cup.:)

pengstrom691 — 2020-12-11 16:18:46 UTC

why

lvanboskirk901 — 2020-12-11 17:06:36 UTC

condensation was the process happening to this can. The water vapor in the air got connected to the coldness of the can which then that water vapor created water droplets. those continued to get bigger and bigger until they got to the point where they dripped

rhempel922 — 2020-12-11 17:06:47 UTC

condensation because when you take the can out of the fridge its warming up to room temperature and when things warm up they make condensation and thats all the evidence i have because i completly forgot why condensation happen

awagner524 — 2020-12-11 17:07:06 UTC

The cold liquid in the soda can and the room temperature created condensation and then water droplets.

asharkey175 — 2020-12-11 17:07:19 UTC

The liquid that is sitting on the outside of the can is called condensation. The cold can drained the energy out from the air, causing the molecules of water to form on the can.

goswalt417 — 2020-12-11 17:07:41 UTC

I think that it was condensation that occurred, this would happen by energy being transferred out of the gas.

eboring743 — 2020-12-11 17:07:43 UTC

the cold can got energy transferred into because it was in the room temperature room, but not enough to phase change? So condensation happens? sorry I don't remember.

mwand695 — 2020-12-11 17:07:55 UTC

The liquid on the outside was condensation because the drink was colder than the air surrounding it. Since the can of soda was colder than the air around it energy was taken away which caused water to form on the outside of the can.

nstevens649 — 2020-12-11 17:07:56 UTC

I think that condensation was because the drink is having energy taken away because it went from cold to room temp

2020-12-11 17:08:22 UTC

The reason the liquid got onto the surface of the can is because the cold liquid was heated by the air around it bringing it to room temperature causing a phase change in the liquid inside the can making the liquid evaporate into a gas and then condensate on the side of the can making small droplets of water.

jheldridge261 — 2020-12-11 17:08:27 UTC

Condensation because when you have a cold drink and gas molecules come near the can it's so cold that the gas molecules will freeze on the can and that's why their was water on the cup.

mmarti730 — 2020-12-11 17:08:36 UTC

so the temperature of the room and the cold soda will have made condensation and will have start to make water droplet

jhansen715 — 2020-12-11 17:09:24 UTC

the liquid on the side of the cup are water vaper because when water vapor around the cup got close to the side the water vapor froze and its freedom of movement was changed then the water droplets turned from a gas to a liqiud

aklug717 — 2020-12-11 17:09:36 UTC

The thin layer of liquid is actually condensation. the gas in the air has hit the cup, then the cup gas and cup exchanged energy, the cup had less for it was cold. when the gas loosed most of its energy it turned into liquid. I think the gas would have a strong molecular attraction, because it turned into a liquid after losing very little energy.

rjackson193 — 2020-12-11 17:09:53 UTC

ckeiser965 — 2020-12-11 18:35:22 UTC

jbosley554 — 2020-12-11 18:37:12 UTC

I think the air around the can cooled in the fridge, causing condensation to take place, forming water droplets on the can.

pgreen180 — 2020-12-11 18:37:32 UTC

The soda can was wet because the outside of the can and the outside of the can the gas from outside turned into a liquid molecules causing soda can to have condensation.

omcklem186 — 2020-12-11 18:37:51 UTC

The liquid on the outside of the soda can is water and it got there in a process called condensation. In one of the labs we did we saw that when we had hot water in one cup and put another cup on top, after a while it caused tiny water droplets to form of the top and side of the cup forming condensation.

agriffith223 — 2020-12-11 18:38:00 UTC

The liquid got on the outside of the can because of more kinetic energy and it got warmer which made condensation happen.

sswanda380 — 2020-12-11 18:38:02 UTC

because the can is cold the water in the air changed to a liquid.

gziegenbein994 — 2020-12-11 18:38:26 UTC

the liquid is the soda but as a liquid and the liquid evaporated then stuck to the can then dripped onto the desk into a liquid again.

swestbrook956 — 2020-12-11 18:38:45 UTC

the water vapor turned into a liquid known as condensation which a appeared on the outside of the can

ckeiser965 — 2020-12-11 18:38:51 UTC

because the drops happen from the can and it is at a temp and then it get warmerd up from the around it and then the coditsion happens. then the water molecules from the drops of water and then they go down the can

hamaro008 — 2020-12-11 18:38:55 UTC

The liquid on the cup was condensation. They got there because the temperature in the air around the cup changed. It got colder, and so did the molecules. This made the molecules have a lower freedom of movement, causing it to change phases into a liquid. These tiny droplets of water then started forming on the outside of the can.

kcaffery904 — 2020-12-11 18:38:57 UTC

The thin layer of liquid is condensation. The water molecules were moving around each other which was making it a liquid. The soda was colder than the atmosphere which was causing the droplets to occur. The molecular attraction was strong enough to from water droplets on the outside of the can.

ashukert763 — 2020-12-11 18:39:14 UTC

it might be because the can is colder than the rooms temp. this is called condensation and it can also happen on hot drinks too. it was also having energy taken away from it and that made it cold

mpeterson481 — 2020-12-11 18:39:37 UTC

I think the liquid was condensation. The water vapor got too heavy so the water had to drop from a gas.

rparris773 — 2020-12-11 18:39:53 UTC

The Liquid on the outside of the cup is condensation it comes from the water vapor that collects in the air. This happened because the molecules on the inside of the cup are colder than the ones outside causing condensation to happen.

ojuhel747 — 2020-12-11 18:39:59 UTC

Condensation from the liquid inside the can was very cold. And it's molecules were probably moving in place very close together. The kinetic energy of the liquid inside the can was very low but not low enough to cause a phase change. The attraction of the liquid was probably weak.

kgillespie469 — 2020-12-11 18:40:10 UTC

The liquid on the soda can is water. When the soda was in the fridge the gas was cold, so when they took it out the gas was still cold. But the gas was exposed to the room temperature and the temperature warmed up. So the gas is phase changing into a liquid, condensation.

kkoenig534 — 2020-12-11 18:40:15 UTC

I believe that the can was wet because of condensation. Condensation is the process where water vapor (gas) cools down to the point it goes back to the phase liquid. Since the can was cold, the process begun outside of the can, so that the water vapor is cooling down and slowly turning into droplets and being visible to the naked eye since it becomes a liquid.

jbedel711 — 2020-12-11 20:25:53 UTC

The type of liquid on the can was condensation. which is water that is attracted to the can.

mroberts276 — 2020-12-11 20:26:11 UTC

i belive the water that was mixed with the chemicals that make soda evaporated and when it did it stuck to the cool surface of the can slowing down the molecules condenating back into water making the can wet

tschwisow310 — 2020-12-11 20:26:38 UTC

The water attracted to the can is from condensation

odill155 — 2020-12-11 20:26:51 UTC

The water on the outside of the can is water, this is formed by condensation. Little air molecules that float through-out the air holds water in them. The water changed from a gas phase to a liquid phase.

alichtenberger795 — 2020-12-11 20:26:52 UTC

condensation cause this process. What I think happened was the air around the can got cold so the molecules changed phases into a liquid. This means that the freedom of movement changed and also the way the molecules move.

hnelson869 — 2020-12-11 20:27:03 UTC

The can was wet because it went through a process called condensation which is what happens when a substance gets really hot or cold and small water droplets form.

escott273 — 2020-12-11 20:27:04 UTC

The liquid on the can is water. There was gas in the air and when it touched the cold can energy transferred out of the air and into the can cooling down the air and making it become a liquid.

kromero141 — 2020-12-11 20:27:49 UTC

I think the liquid is water. The outside of the can was wet because it was going through condensation. In the description, it describes mainly everything that happens when water condensates. The water could have been a gas a cooled down to the point where it became a liquid again on the outside of the can.

atate089 — 2020-12-11 20:27:50 UTC

I believe that water vapor got rid of enough kinetic energy that the water vapor changed phases. The molecules slowed down and the gas became a liquid or condensation on the outside of the pop can.

zgunsolley905 — 2020-12-11 20:27:59 UTC

The cold liquid on the office worker's cup is from the water vapor in the air starts to go through the process of condensation so that the water vapor from the air goes through phase change on the cold can. This is because condensation happens when water vapor is exposed to a cold surface (in this case the can) and then it starts transferring out the kinetic energy until it loses enough energy to phase change. That is why water started to form on the office worker's can.

gdahlhauser109 — 2020-12-11 20:28:10 UTC

The water was condensated. This happens when the cold liquid inside of the can gains kinetic energy and then created into water vapor which then appears on the outside of the can.

jhickam588 — 2020-12-11 20:28:48 UTC

water was on his desk. The water got there by going through the process of condensation. First The can got hot and than water drop lets stated to form and the molecules gained energy and turn into a liquid than that liquid formed and started to drop down on his desk
