Aim: to observe contraction in gases.
Equipment: aluminium can, scissor tongs, bunsen burner, heatproof mat, tripod, gauze mat, an open container of water.
hypothesis: the can will shrink.
Equipment: aluminium can, scissor tongs, bunsen burner, heatproof mat, tripod, gauze mat, an open container of water.
hypothesis: the can will shrink.
- 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.
Observations: the water in the can started to boil when heated, it started to steam then when it was placed in cold water it shrinks and squished together.
Explanation:
- the boiled because it was being heated by the bunsen, causing the particles to vibrate alot and move around.
- The can contracted because it was going from hot to cold, cooling them down too fast and they got small and stuck together.
