Behaviour of Matter - Contraction The imploding can

The Imploding Can 

Aim: To observe contraction in gases.

Equipment: Aluminium Can, Scissor Tongs, Bunsen Burner, Heatproof Mat, Tripod, Gauze Mat & and open Container of Water.

Method: 

1. Set up the bunsen burner underneath a tripod and gauze mat.

2. Pour Approximately 50-60mL of water into your can.

3. Heat the can of water until you see steam is escaping from the top.

Carefully grip the can with scissor tongs. Ensure you have a firm hold of the can before lifting it off

the gauze mat.

4. Quickly, but carefully, invert the can as you plunge it into a container of water.

Observations: 

We didn't put it into the water fat enough causing it not to work but what was supposed to happen if we did it right was that the cans sides would cave in on itself.

Explanation:
When particles are heated they begin to move faster eventually the Bunsen burner made the gas inside the can go a lot faster. Causing it to steam then when we put the top into the cold water the water cooled the can making the gas go closer together causing the can to implode.
