March 6, 2015Homework: NoneDo Now: Agenda- Write H.WTake (Magic Square sheet, section 3 assessment questions (2a, 2b, 2c), and graph.

On Section 3 Assessment pg. Describe what is happening to the balloon in the hot pot- What gas laws are present?

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
