Question

Is latent heat positive or negative?

Answer 1

Explanation:

Latent Heat positive or negative

1. The latent heat of condensation is equal to the opposite sign of the latent heat of vaporization.

2. Since heat is released by the substance, the latent heat of condensation is always negative, while the latent heat of vaporization

is always positive because of the absorption of heat by the substance.

3. Latent heat of fusion is negative because heat is released by the substance, whereas the latent heat of melting is positive because

heat is absorbed by the substance.
