Science Activity: Gases and Changes of State

We have 2 liters (2L) of a gas sealed in a container. We place the container inside a closed room and open the lid.

• Explain what happens to the gas.

• Will the volume be different now? Explain your reasoning.

Identify the type of transformation (or 'change of state') that occurs in the following cases:

1. A gel air freshener (when it releases its smell).

2. Condensation forming on the shower mirror.
