1.	When 1 kg of ice at 0^@ C melts to water at 0^@ C, the resulting change in its entropy, taking latent heat of ice to be 80 "cal/".^@C is ____
Answer» `273 "cal"/K` `8xx104"cal"/K` `80"cal"/K` `293"cal"/K` Solution :Change in ENTROPY `dS=(dQ)/T` `THEREFORE DeltaS=(DeltaQ)/T=(mL_f)/273` `therefore DeltaS=(1000xx80)/273`=293 cal/K
