Homework Statement

Consider the heating curve for H2O.
a. As heat is added to melt ice, does the the temperature change? Explain what happens to the heat that is added.
b. For the same amount of H2O, does it take more to melt ice or vaporize water? Explain why.
c. Is the fusion of ice endothermic or exothermic ?

Homework Equations





The Attempt at a Solution


a. Obviously the temperature doesn't rise.but what is happening to the heat that is added?
are they adding up to have enough energy to change the solid into liquid?

b.From the graph, it seem like it take more heat to vaporize the water, is it because the process requires the separation of Hydrogen bonds, which take a lot of energy in comparison to just melt the ice, where the bonds are just being loosen up?

c. It take heat to melt the ice, so it is endorthermic.

thanks for your time.

Not at all, thank you.

I don't get your reply. Are the answers alright or not at all?
