Calculate the enthalpy change, change of H, for the process in which 37.1 g of water is converted from liquid at 4.4 degrees C to vapor at 25.0 C.

water change in H=44 kJ/mol at 25 degrees C and s=4.18 j/(g*C) for H2O.

How many grams of ice at -20.6 C can be completely converted to liquid at 29.6 C if the available heat for this process is 4.26×10^3 kJ ?

For ice, use a specific heat of 2.01 J/(g*C) and change in H= 6.01 kJ/mol.
