Problem Suppose that 1.02 g of rubbing alcohol (C3H8O) evaporates from a 55.0-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 ofthe alcohol K comes only from the aluminum block and that the alcohol vaporizes at 25 °C.
