Latent Heat and Specific Latent Heat

This lesson Covers phase transitions at constant temperature, focusing on the specific latent heat of fusion (Lice​) and vaporisation (Lsteam​), experimental determination of fusion, and the physical effects of pressure, expansion, and impurities on melting/freezing points.

Latent Heat and Specific Latent Heat:

• Define latent heat and specific latent heat of fusion and vaporisation.

• Describe an experiment to determine the specific latent heat of fusion of ice.

• Explain regelation and how pressure and impurities affect freezing points.
