@BriellShaw There was something wrong with my internet connection.
Well! Your answer to my second question was not correct.
When some boiling water GETS ENERGY, the energy is consumed ONLY TO CHANGE LIQUID TO GAS. This DOESN'T CHANGE water's temperature.

The situation when steam changes to gas is COMPLETELY A REVERSE process.
Can you guess what would be the answer of your question?
