This diagram shows a cooling curve for water. Look for the flat sections of the heating or cooling curve to find the temperatures at which the substance changes state.

Students will be able to explain that cooling water can change it to ice and that heating ice can change it back to liquid water. Students will be able to explain that this process can also happen to ...

Latent heat can be measured from a heating or cooling curve line graph ... If this energy had caused 100 g of water to evaporate, what is the latent heat of vaporisation of water?
