Latent heat — Science definition
Defined in 2 courses:
- Energy per amount of substance associated with a phase change at nearly steady temperature. (Physical Science: Matter, Forces & Energy)
- Energy per unit mass for a specified phase change. (Physical Science: Chemistry)
Where it is taught
- Heating Curves & Energy During Phase Change — Phases of Matter, Physical Science: Matter, Forces & Energy, Grade 8
- Heating Curves & Phase-Change Energy — States of Matter & Gases, Physical Science: Chemistry, Grade 11
In use
During a phase change, use q = mL, where L is specific latent heat, or q = nΔHphase when molar phase-change enthalpy is supplied.
