Wärme of Vaporization Rechner — Formel
## Heat of Vaporization
The heat of vaporization is the energy needed to convert a liquid to gas at constant temperature.
### Formula
**Q = m * L_v**
For water, L_v = 2,260,000 J/kg = 2260 kJ/kg, much larger than the heat of fusion because more energy is needed to fully separate molecules.

Lösungsbeispiel
Boiling 1 kg of water at 100°C.
- Q = m * Lv
- Q = 1 * 2260000
- Q = 2,260,000 J = 2260 kJ
