How much heat (in kJ) is required to warm 10.0 g of ice, initially at -13.0 ∘C, to steam at 109.0 ∘C? The heat capacity of ice is 2.09 J/g⋅∘C and that of steam is 2.01 J/g⋅∘C. The heat capacity of liquid water is 4.18 J/g⋅∘C. This substance has an enthalpy of fusion of 6.01 kJ/mol and an enthalpy of vaporization of 40.7 kJ/mol.

bobpursley · Answer

add the heats: heat to warm up ice to 0C heat to melt ice at 0C heat to warm water to 100C Heat to convert water to steam at 100C Heat to warm steam from 100 to 109C
