1. March 6, 2015 Homework: None Do Now: Agenda- Write H.W Take (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?

2. 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!
