Section 3 assessment Ques.
2a: At constant temperature, when gas pressure increases, gas volume decreases.
2b: When temperature increases gas particles move faster, colliding more with the sides of the container, causing greater pressure.(If the container can not expand, at a constant volume)
2c: Do not completely inflate the balloons because as the temperature increases over night the volume will increase- inflate too much and balloon will burst!

1. Charles’ Law• Volume (of gas) and Temperature– When temperature goes up, volume
goes up– When temperature goes down,
volume goes down
