Latent heat is thermal energy absorbed or released during phase changes without temperature change. It's crucial in heating systems, refrigeration, and water cycles.
Formule
The calculator applies Q = m × L for melting, vaporization, or sublimation
- Q
- m × L for melting — m × L for melting
- L
- L value — Variable used in the calculation

Veelgestelde vragen
Why doesn't temperature change during boiling?
Energy goes into breaking molecular bonds to transition from liquid to gas, not increasing molecular motion.
Is latent heat the same for all substances?
No, different substances have different latent heat values depending on molecular structure and intermolecular forces.
