How it works
Energy for a phase change at the transition temperature is Q = mass × specific latent heat.
Input definitions
- Mass changing phase (kg)
- Enter the value in the labeled unit.
- Specific latent heat (J/kg)
- Enter the value in the labeled unit.
A worked example
- Mass changing phase (kg)
- 2
- Specific latent heat (J/kg)
- 334000

Common questions
Does this include warming the material first?
No. Calculate sensible heating separately. Latent heat covers only the phase change at the relevant transition conditions.
How does Latent heat for a phase change work?
Energy for a phase change at the transition temperature is Q = mass × specific latent heat.
What should I check before using Latent heat for a phase change?
Ideal educational model in the stated SI units. Real equipment, structural design and safety decisions need appropriate professional analysis; losses are excluded unless entered.
