Topic 2-lesson 3: Gas Behavior

1.  What happens to the particles in a volleyball as it sits in the hot sun?

• the particles slow down and the ball deflates some

• the particles move faster and the ball becomes firm

• nothing changes

2.  What does pressure mean? pg. 67

• gas particles are vibrating

• gas particles have an inward pull on the wall of the container

• gas particles push outward on the wall of the container

• may the force be with you

3.  What does inversely proportional mean? pg. 73

• as one variable increases, the other variable increases

• as one variable increases, the other variable decreases

• one variable doesn't affect another variable

• the universe is getting larger

4.  What does Charles's law state? pg 69

• at a constant pressure, if temperature increases, volume decreases

• at a constant pressure, temperature and volume never change

• at a constant pressure, if temperature increases, volume increases

• at a constant temperature, pressure and volume are equal.

5.  Charles's Law is an example of a directly proportional relationship.  What does directly proportional mean? pg. 69

• as one variable increases, the other variable increases

• as one variable increases, the other variable decreases

• one variable doesn't affect another variable

• the universe is getting larger

6.  What does Boyle's Law state? pg. 71

• at a constant temperature, as volume decreases, pressure increases

• at a constant temperature, as volume increases, pressure increases

• at a constant temperature, volume equals pressure

• at a constant pressure, as temperature increases, volume increases

7. What is an example of Charles's law? pg. 69

• a hot air balloon (A)

• a balloon lowered into liquid nitrogen (B)

• a tire pump (C)

• Both A and B
