The equation to be used to
calculate the heat required to vaporize 1 gram of water at 100 degrees eclsius
and 1 atmosphere is the enthalpy. It is represented as H =
mCpT
where H is the heat released after phase change, m is
the mass of the substance, Cp is the specific heat capacity of the substance
and T
is the change in temperature.
H = mCpT
H = (1g/1000g/kg)(4.184kJ/kg-K)(100
H = 0.335 kJ
