1.Suppose that 1.08 g of rubbing alcohol (C3H8O) evaporates from a 70.0 g aluminum block.

If the aluminum block is initially at 25 °C, what is the final temperature of the block after the evaporation of the alcohol? Assume that the heat required for the vaporization of the alcohol comes only from the aluminum block and that the alcohol vaporizes at 25 °C. Heat of vaporization of the alcohol at 25 °C is 45.4kJ/mol

2.Propane has a normal boiling point of -42.0 °C and a heat of vaporization (ΔHvap) of 19.04kJ/mol. What is the vapor pressure of propane at 40.0 °C?

3.How much heat (in kJ) is required to warm 12.0 g of ice, initially at -10.0 °C, to steam at 108.0 °C? The heat capacity of ice is 2.09 J/g⋅°C and that of steam is 2.01 J/g⋅°C.
