Experiment 1. Observe the impact of temperature on gases in the scenario where the volume of the container can change. 1. Place some dish soap on a small plate and dip the opening of the plastic bottle in the soap in order to form a film across the bottle opening. 2. Squeeze the bottle slightly and observe the movement of the film. The pressure inside and outside the bottle is the same. Therefore, when you reduce the volume by squeezing, the air particles collide with the film and increase the volume (back to its original volume) 3. Verify that the soap film is still present. If not, dip the bottle in the soap, so you have a soap film. 4. Place hot water in a bowl and then hold the bottle in the water (only the bottom part needs to be in contact with the hot water). Observe what happens to the soap film. 5. In your words, write down a molecular level description that explains what you just observed.
