Latent Heat Calculator

Find heat for a phase change.

Heat required (J) 167,000

Heat required (kJ) 167

Formula: Q = m · L

Step-by-step with your numbers:

1. Values used:

2. Mass = 0.5

3. Latent heat = 334,000 J/kg

5. Heat required = Mass x Latent heat = 0.5 x 334,000 = 167,000J

6. Heat required = 167kJ

Did we solve your problem today?

Latent heat is the energy for a phase change at constant temperature.

The math behind it

Q = mass × latent heat. Ice melts at L = 334,000 J/kg; water boils at 2,260,000 J/kg.

0.5 kg ice melting → 167,000 J.

Why constant temperature?

The energy breaks bonds rather than raising temperature.
