After doing the experiment

What causes gass pressure?
What will happend to the gas pressure in a bottle and balloon if the temperature of the gas increases?
What will happen to the gas pressure in a bottle and balloon if the temperature of the gas decrease?
Give a conclussion from your experiment.

The expanding gas blows up the balloon. The hot water causes the air inside the bottle and balloon to also heat up. The faster moving particles inside the bottle start to move faster and faster and soon they expand to fill the balloon. Gas pressure is the pressure that results from collisions of gas particles with an object. Inside the balloon, the gas particles collide with the balloon's inner walls. It is those collisions which keep the balloon inflated.
Increasing the temperature of the gas in a balloon will cause the gas molecules to move more quickly. And that's what makes balloons inflate with boiling water. This can be easily understood by visualising the particles of gas in the container moving with a greater energy when the temperature is increased. This means that they have more collisions with each other and the sides of the container and hence the pressure is increased.
The expanding gas explodes the balloon. When you put the bottle in cold water, the air becomes cold again. Cool air doesn't have much energy, so it contracts and the balloon deflates with it.
Putting the bottle in hot water causes the air molecules inside to heat up and begin taking up more space, causing air to enter the balloon and inflate it. When you move the bottle into the cold water, the air molecules cool back down and take up less space

1. Gas pressure is the pressure that results from collisions of gas particles with an object. Inside the balloon, the gas particles collide with the balloon's inner walls. It is those collisions which keep the balloon inflated. If the gas particles were to suddenly stop moving, the balloon would instantly deflate.

2. Increasing the temperature of the gas in a balloon will cause the gas molecules to move more quickly. They'll collide with the walls of the balloon more frequently and rebound with greater force. Both will increase the pressure.

3. The frozen balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases. This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.

4. When I tried this experiment, if a glass bottle with a balloon attached to the top lid was placed in boiling water, I think there was steam or gas that filled the balloon so it could balloon/expand. Meanwhile, if you put it in cold water, the balloon immediately deflates because there is no pressure

1. From the force exerted by gas molecules, colliding with the surfaces of objects. A large number of collisions in a short time, which can result in a high pressure. When the temperature outside the glass object increases, the steam also increases, making the balloon expand due to the influx of gas.

2. When the temperature increases, the balloon expands, when it experiences heat gain or gets hot.

3. When the temperature becomes low, the steam slowly disappears, the temperature of the glass bottle also becomes cooler, the balloon which was initially inflated, slowly loses gas and deflates.

4. Heat half the water, until it boils, then put a glass bottle that has been covered by a balloon, when the water boils, there when you see the process, where the temperature increases and releases steam, the balloon becomes inflated, then when we move the glass class and the inflated balloon into the basin filled with cold water, the steam slowly dissipates, the temperature of the glass bottle becomes low, and the balloon deflates. Gas is also obtained from heat energy.

1.Gas pressure is caused by the force exerted by gas molecules colliding with the surfaces of objects. Although the force of each collision is very small, any surface of appreciable area experiences a large number of collisions in a short time, which can result in a high pressure.

2.The balloon will be filled with gas particles produced by the heat generated from boiling water.

3.The balloon will become small again because the particles are gone, because the temperature of the boiling water decreases.

4.Balloons can expand because there are gas particles and pressure generated from boiling water and when the boiling water is replaced with cold water, the balloon will shrink again because the gas particles are reduced and the pressure is lost.
