What Is Latent Heat?
Latent heat is the energy required for a substance to change state (melting, boiling) without its temperature changing.
How is it calculated?
How Is It Calculated?
Q = m × L
L: latent heat of fusion or vaporization.
- Enter the mass and the relevant latent heat value.
Frequently Asked Questions
Why does temperature stay constant during a phase change?
The supplied energy is used to break molecular bonds, so the temperature does not change temporarily.
