1. A pot of very cold water (0째C) is placed on a stove with the burner adjusted for maximum heat. It is found that the water just begins to boil after 2.0 min. How much longer will it take the water to completely boil away?
2. An aluminum block slides along a horizontal surface. The block has an initial speed of 10 m/s and an initial temperature of 10째C. The block eventually slides to rest due to friction. Assuming all the initial kinetic energy is converted to heat energy and all this energy stays in the block, what is the final temperature of the block?
