A heating coil is immersed in a 100 g sample of H2O(l) at 1 atm and 100∘C in a closed vessel. In this heating process, 60% of the liquid is converted in to gaseous form at constant pressure of 1 bar. Densities of liquid and gaseous water under these condition are 1000kg/m3,0.60kg/m3 respectively. magnitude of the work done for the process is :
