Question 8

As the temperature of a container with a gas inside increases, the pressure of the gas _________.

Answer 8

increases

Question 9

Describe what happens as the temperature of a container with a gas inside increases.

Answer 9

The gas particles travel faster and collide with the walls of the container more frequently, and with more force.

Answer 12

p₁V₁=p₂V₂

Question 13

Give 2 ways of increasing pressure.

Answer 13

1. Increasing the temperature of the container.
2. Decreasing the volume of the container.

Question 14

What does increasing the temperature of the container do, causing the pressure to increase?

Answer 14

increases the force of each collision

Question 15

What does decreasing the volume of the container do, causing the pressure to increase?

Answer 15

increases the frequency of collisions
