Heat Curve of Water

Postby Anika_Patel_1G » Sat Jan 13, 2018 9:27 am

Will somebody explain why the vaporization section in the heat curve of water is much longer than the fusion part? In other words, why does it take longer for a liquid to become a gas as than a solid to become a liquid?

It takes far more energy to excite liquid water molecules and break the bonds between them to cause vaporization than to break the crystalline-structured bonds between water molecules found in ice so the heating curve is much longer for vaporization.

We only need to know this concept, not that actual values for this correct?

I don't think Dr. Lavelle will expect us to remember the exact values but I think he does want us to know the concept.
