Expansion
Applying heat, causes particles to spread out
Contraction
Contraction makes the particles to cool down, causes the space to be denser.
Next, we had to do the experiment, 'The Imploding Can' experiment.
Aim: To observe contraction in gases
Hypothesis: I think the water is going to cool down because the boiling water will go to a container of water which is cooler than the boiling water.
Equipment:
- Aluminum Can
- Scissor Tongs
- Element
- Heatproof Mat (just in case)
- Beaker
- Container of water
Method:
- Set up an Element.
- Pour 60ml of water into your empty can. It should be no more than ¼ full.
- Heat the can of water until steam comes up.
- Carefully, grip the can with scissor tongs. Make sure you have firm hold of the can before lifting it off the element.
- Quickly, but carefully, tip the can as you plunge it into a container of water.
Results:
The aluminium can imploded when it went into the container of water.
Discussion:
The purpose of it imploding is because the boiling water suddenly became cool which caused it to contract.
