The entropy change associated with the conversion of 1 kg of ice at 273 K to water vapours at 383 K is :
(Specific heat of water liquid and water vapour are 4.2 kJ K−1kg−1 and 2.0 kJ K−1kg−1 ; heat of liquid fusion and vapourisation of water are 344kJ kg−1 and 2491 kJ kg−1 , respectively).
(log 273 = 2.436, log 373 = 2.572, log 383 = 2.583)
