Latent heat is thermal energy absorbed or released during phase changes without temperature change. It's crucial in heating systems, refrigeration, and water cycles.
Formel
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
Steg-för-steg-guide

Lösta exempel
Ingång
m = 1 kg water, L_vap = 2,260 kJ/kg
Resultat
Q = 2,260 kJ
Energy to boil 1 kg water
Vanliga misstag att undvika
- ✕Confusing latent heat with specific heat capacity
- ✕Using sensible heat calculations for phase changes
Vanliga frågor
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.
