Definition: The energy required to transform a given quantity of a substance into a gas or back into a liquid.

Explanatioln/Notes: The amount of energy it takes to transform a liquid into a gas or back into a liquid.

Formula: Q=M(Hv)

Units:
  • Q=Heat
  • M=Mass
  • Hv=Heat of vaporization
  • J=Joules (energy)

Everyday Example: When water boils into steam in a teakettle

Sample Problem:
Mass= 5g Hv = 2260 J/g
Q=M(Hv)
Q=5g(2260 J/g)
Q=11300 J
