Question

Is the concept of latent heat applicable during transformation of gaseous phase to liquid phase and from liquid phase to solid phase?

Where does the latent heat go during these transformations?

Answer 1

Yes. The concept of latent heat is applicable during both:

• Gas → Liquid (condensation): latent heat of vaporization is released.
• Liquid → Solid (freezing): latent heat of fusion is released.

During these changes, the substance does not lose temperature. Instead, the latent heat is given out to the surroundings. This released heat warms the surrounding air or any object in contact with the substance.
