To convert 100 mg of water at 60 degree Celsius to steam at 100 degree Celsius, we have to first heat the water from 60 degree Celsius to 100 degree Celsius and then add more heat to convert it from liquid state to gaseous state.

The specific heat capacity of liquid water is 4.1855 [J/(g*K)]. And its heat of vaporization is 2257 kJ/kg.

To increase temperature of 100 mg by 40 K, the heat required is 4.1855*40*0.1 J and to convert 100 mg of water to steam, we require 2257*10^3*10^-4 J

The total heat required is 16.742 + 225.7 J = 242.442 J

The required heat is 242.442 J
