really simply because all of the heat is contained in that phase change.

For instance, water takes about 100 times the energy to change phase (steam or ice) as it does to raise or lower 1 degree. Refrigerants are similar. You can focus on a specific temperature and provide a fairly solid state process.

What she/he said.

It takes more energy to evaporate a pound of water than it does to melt a pound of steel.

The phase change is where most of the heat transfer happens.
