solid: ice
liquid: water
gas: steam]]> 2017-04-19 14:19:44 UTC https://padlet.com/54808/3b45i6dy7pu7/wish/167023051 54808 https://padlet.com/54808/3b45i6dy7pu7/wish/167023139 Humanity uses the freezing and boiling point for everyday things all the time. We figured out early to boil water to make it clean, and now we use it to cook things in all the time. We use ice to put in our glasses of water to keep it cool, to treat injuries and to keep food from spoiling.]]> 2017-04-19 14:19:57 UTC https://padlet.com/54808/3b45i6dy7pu7/wish/167023139 54808 https://padlet.com/54808/3b45i6dy7pu7/wish/167023252 We can change the freezing and boiling point of water by adding solutes in. In colder places salt is commonly used to clear the roads of snow or salt. Pressure can also affect boiling temperature a lot like when you put a lid on a pot to boil water while cooking]]> 2017-04-19 14:20:14 UTC https://padlet.com/54808/3b45i6dy7pu7/wish/167023252 54808 https://padlet.com/54808/3b45i6dy7pu7/wish/167023331 Its possible to calculate the freezing and boiling point of a liquid using morality and vice versa. A higher morality will increase the boiling point and decrease the freezing point.]]> 2017-04-19 14:20:26 UTC https://padlet.com/54808/3b45i6dy7pu7/wish/167023331 54808 https://padlet.com/54808/3b45i6dy7pu7/wish/167023437 the water cycle works by water from the ground and sea evaporation into the atmosphere and then coming back down as snow or rain and repeating.

temperature affects the water cycle because the hotter it is,the more water evaporates. 

an example of this is when the temperature is very low (like -30 c) and you throw a boiling pot of water into the air, the water will turn to steam before it can hit the ground]]> 2017-04-19 14:20:40 UTC https://padlet.com/54808/3b45i6dy7pu7/wish/167023437 54808 https://padlet.com/54808/3b45i6dy7pu7/wish/167026887 2017-04-19 14:30:04 UTC https://padlet.com/54808/3b45i6dy7pu7/wish/167026887 54808 https://padlet.com/54808/3b45i6dy7pu7/wish/167029932 2017-04-19 14:40:41 UTC https://padlet.com/54808/3b45i6dy7pu7/wish/167029932 54808 https://padlet.com/54808/3b45i6dy7pu7/wish/168385276 the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.]]> 2017-04-26 14:29:07 UTC https://padlet.com/54808/3b45i6dy7pu7/wish/168385276 54808 https://padlet.com/54808/3b45i6dy7pu7/wish/168385448 Small insects such as the water strider can walk on water because their weight is not enough to penetrate the surface.

Surface tension is responsible for the shape of liquid droplets. Although easily deformed, droplets of water tend to be pulled into a spherical shape by the cohesive forces of the surface layer. So when you see dew drops on the grass in the morning this is what you're seeing

In the Olympics, divers need machines in the pool to produce tiny ripples and air bubbles to soften the water and lower its surface tension.]]> 2017-04-26 14:29:29 UTC https://padlet.com/54808/3b45i6dy7pu7/wish/168385448 54808 https://padlet.com/54808/3b45i6dy7pu7/wish/168387378 Tap water is usually around 72 to 73 dynes/cm. There are places around the world that claim to have special water. They say their water has a lower surface tension and less colloidal minerals and thus makes them healthier and live longer. Whether for this reason or not, these people have been known to live longer lives. Because of the belief that lower surface tension is healthier, there are now websites where we can buy supplements to lower our waters surface tension.]]> 2017-04-26 14:34:08 UTC https://padlet.com/54808/3b45i6dy7pu7/wish/168387378 54808 https://padlet.com/54808/3b45i6dy7pu7/wish/168387553  Inter-molecular forces (IMFs) are the forces which mediate interaction between molecules. The primary intermolecular force present in water is hydrogen bonding. The water molecules attract one another due to the water's polar property. The hydrogen ends, which are positive in comparison to the negative ends of the oxygen cause water to "stick" together]]> 2017-04-26 14:34:34 UTC https://padlet.com/54808/3b45i6dy7pu7/wish/168387553 54808 https://padlet.com/54808/3b45i6dy7pu7/wish/168387844 Surface tension affects evaporation rate so water with a higher surface tension takes longer to evaporate.]]> 2017-04-26 14:35:17 UTC https://padlet.com/54808/3b45i6dy7pu7/wish/168387844 54808 https://padlet.com/54808/3b45i6dy7pu7/wish/168890287 2017-04-28 14:27:07 UTC https://padlet.com/54808/3b45i6dy7pu7/wish/168890287 54808 https://padlet.com/54808/3b45i6dy7pu7/wish/168890462 2017-04-28 14:27:47 UTC https://padlet.com/54808/3b45i6dy7pu7/wish/168890462
