question

Using data from the accompanying table find the increase of enthalpy for 100 g of H_2 O going from ice at - 10°C to liquid water at + 15°C. Assume that the molar heat of fusion of ice is 6.02 kJ. Heat capacity in joules per mole-degree for various substances at the temperatures indicated H_2 O(s)at239°k33.30 H_2 O(s)at271°k37.78 H_2 O(l)at273°k75.86 H_2 O(l)at298°k75.23 H_2 O(l)at373°k75.90 H_2 O(g)at383°k36.28
