Question

What happens to molecular energy(heat) in water when water vapor becomes a liquid?

Water vapor absorbs heat energy.

Water vapor retains the same heat energy.

Water vapor gives up heat energy.

As water's mass increases it absorbs energy.

Answer 1

When water vapor condenses into liquid water, it gives up heat energy. This process is called condensation, and it releases latent heat to the surrounding environment. So, the correct statement is:

**Water vapor gives up heat energy.**
