In science we have been exploring matter, and the way it changes state between liquids, solids, and gases.Monday we wondered, how does temperature affect the rate of evaporation of liquid?
We began with two cups of liquid (water) - one hot, and one cold. To trap the evaporating gas, we put larger cups over the smaller cups. We used food coloring to remember which was the hot water and which was the cold.
We discovered that the hot water evaporated more quickly. Why do you think this was? Post your ideas in the comments!
Cause the hot water already has energy in it.

I think it was because the hot water got the molecules excited and they evaporated and became gas.

Sumin,
ReplyDeleteI notice that the cold water does'nt evaporate but I saw that the hot water evaporate and because of capturing the gas we could see the gas well.
Amanda The hot water evaporated faster in warm water because it allready has energy.
