Latent Heat
The latent heat is the heat absorbed or given out at constant temperature during the change of state of matter.
- When a solid melt, heat is absorbed but the temperature remains constant.
- When a liquid is boiling, heat is also absorbed but the temperature again remains constant.
- The heat absorbed or given out at constant temperature during the change of phase is known as latent heat.
- The heat energy that releases during condensation or boiling is called the latent heat of vaporization.
- The heat energy that releases during freezing or melting is called the latent heat of fusion.
