Question
Which of the following processes involves latent heat of vaporization?A. BoilingB. MeltingC. FreezingD. Condensation
Solution
The processes that involve latent heat of vaporization are A. Boiling and D. Condensation.
Here's why:
A. Boiling: When a liquid boils, it changes to a gas. This process requires energy, which is absorbed from the surroundings and used to break the intermolecular bonds in the liquid. This energy is known as the latent heat of vaporization.
D. Condensation: This is the process where a gas turns into a liquid. It's the opposite of boiling. When a gas condenses, it releases the energy it had absorbed to become a gas. This released energy is also the latent heat of vaporization.
B. Melting and C. Freezing involve the latent heat of fusion, not the latent heat of vaporization.
