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 4.2kJ K-1 kg-1and2.0 kJ K-1;heat of liquid fusion and vapourisation of water are 334 kJkg-1 and 2491 kJ kg-1, respectively). (log 273 = 2.436, log 373 = 2.572, log 383 = 2.583)

• A. 7.90 kJ kg-1 K-1
• B. 2.64 kJ kg-1 K-1
• C. 8.49 kJ kg-1 K-1
• D. 9.26kJ kg-1 K-1
