Need help with this practice problem. I got the values for the gas to liquid and liquid to solid. Don't know how to do the rest? Heat of Vap and fusion too? No idea!
What is the enthalpy change during the process in which 100.0 g of
water at 50.0 C is cooled to ice at 30.0 C?
The specific heats of ice, liquid water, and steam are 2.03 J/g-K, 4.18 J/g-K, and 1.84 J/g-K,
respectively. For H2O, Hfus = 6.01 kJ/mol and Hvap = 40.67 kJ/mol.
Please show the work. I know the answer is 60.4kJ
Thank you!
