1

If the pressure is kept constant and the temperature is increased, what will happen to the volume?

1

If the pressure is kept constant and the temperature is decreased, what will happen to the volume?

1

If the volume is reduced, what happens to the pressure?

Application task.  I, We, You do...

4

Describe the relationship shown in the graph
As the temperature increases, the volume __________.
This is because the gas particles move around more _, hitting the walls of the container , causing the walls to move outwards and the volume to expand.
+ The relationship on the graph is ________ proportional

Fill in the gaps and rewrite the paragraph

4

Explain the relationship shown in the graph
As the volume decreases, the pressure __.
This is because the gas particles will be closer together so will hit the walls of the more often and apply a greater on the wall of the container.
+ The relationship on the graph is proportional

Fill in the gaps and rewrite the paragraph
