Activity 1 Practical Work Title: Expansion and heat

Purpose

To observe how heating a gas causes it to expand.

This practical activity requires that you wear safety glasses

Materials

  • glass bottle
  • hot tap water
  • balloon

Procedure

1 Fill the glass bottle with hot tap water.

2 Pour out the hot water and quickly stretch a balloon over the mouth of the bottle.

3 Let the bottle cool or place it in a tub of cool water and observe what happens.

Results

Construct a series of diagrams that shows what happened.

Discussion

1 a State whether this is a chemical or physical change.

b Justify your answer.

2 Use the terms expansion and contraction to describe  your observations.

3 Describe what is happening inside the balloon using the particle model.
