Условие

When 100 g of ice melts at $0^{\circ}C$ in a room with $25^{\circ}C$ the entropy change is 159 J/K. What would be the entropy change (in J/K) if this process occurs in a room with the temperature of $30^{\circ}C$? Round up the result to integers (without units). The specific heat capacity of ice is $C_{ice} = 2.060\ J/(g \cdot K)$ and that of liquid water is $C_{liq} = 4.184\ J/(g \cdot K)$.
