Question

When 1 kg of ice at 0^oC melts to water 0^oC, the resulting change in its entropy, taking latent heat of ice to be 80 cal/^oC, is

8 x 10⁴ cal /K

80 cal/K

293 cal/ K

273 cal/ K

Solution

293 cal/ K

Change in entropy

$increment straight S space equals space ml over straight T space equals space fraction numerator 1000 space straight x space 80 over denominator 273 end fraction space equals space 293 space cal space straight K to the power of negative 1 end exponent$
