Presume that 1.02 g of rubbing alcohol (C3H8O) evaporates from a 57.0 g aluminum block. Explain if the aluminum block is initially at 25, Explain what is the final temperature of the block after the evaporation of the alcohol? Presume that the heat required for the vaporization of the alcohol comes merely from the aluminum block as well as that the alcohol vaporizes at 25.
