Aim
to Observe Contraction in Gases
Equipment
Can, Scissor tong, Bunsen burner, Heat Proof mat, tripod gauze mat, open container of cold water,
Method
- Set up your bunsen burner under the tripod and gauze mat.
- pour apox 50-60 ml of water into the can. it should be no more than 1/4 full.
- heat the can of water until steam is escaping from the top.
- carefully grip the can with the tongs. be sure to have a strong grip on it before lifting it off.
- Quickly but very carefully invert the can as you plunge it into the container of cold water.
Hypothesis
I think the can will implode. it will crumple upon itself,
Observations
the water in the can boiled and when we tipped it into the water it imploded on itself like I thought
Explanation
this happened because the air pressure inside the can becomes less than that outside so it crumples in on itself when it got cooled quickly
