The increase in entropy of \( 1 \mathrm{~kg} \) of ice at \( 200 \mathrm{~K} \) which is heated to \( 400 \mathrm{~K} \) (super heated steam) at constant atmospheric pressure, will be :
Given that \( \quad \mathrm{C}_{\mathrm{p}} \) (ice) \( =2.09 \times 10^{3} \mathrm{~J} / \mathrm{kg} \) degree \( ; \mathrm{C}_{\mathrm{p}} \) (water) \( =4.18 \times 10^{3} \mathrm{~J} / \mathrm{kg} \) degree
\( \mathrm{C}_{\mathrm{p}} \) (steam) \( =2.09 \times 10^{3} \mathrm{~J} / \mathrm{kg} \) degree \( ; \)
\( \mathrm{L}_{\mathrm{f}}(\mathrm{C}, 273 \mathrm{~K})=3.34 \times 10^{5} \mathrm{~J} / \mathrm{kg} ; \)
\( \mathrm{L}_{\mathrm{v}}( \) water, \( 273 \mathrm{~K})=22.6 \times 10^{5} \mathrm{~J} / \mathrm{kg} \)
