Heat of Vaporization (Hv)
HEAT OF VAPORORIZATION (Hv): Amount of heat a liquid needs to vaporize (evaporate) or condense one gram of a substance
Reffy: Table B (p. 1)
This means that one gram of water will:
1. Absorb 2260 joules in order to boil/ vaporize (it needs to take in heat in order to evaporate).
Evaporation
Condensation
Heat of Vaporization
works for evaporation and condensation!
2. Release 2260 joules in order to condense (it needs to give away heat in order to condense).
