Specific latent heat
The amount of
energy
required to change the
state
of one
kilogram
of substance with
no change
in
temperature
Specific latent heat of fusion
The
energy
required to change
1 kilogram
of a
substance
from a
solid
to a
liquid
with
no change
in
temperature
Specific latent heat of vaporization
The
energy
required to change one
kilogram
of a substance from a
liquid
to a
vapor
with
no change
in
temperature
Calculating energy change for change of state
Energy for change of state (J) =
Mass
(kg) x
Specific latent heat
(J/kg)
Specific latent heat values
Specific latent heat of
fusion
of
water
=
334,000
J/kg
Specific latent heat of
vaporization
of
ethanol
=
846,000
J/kg
