A 29.7 gram piece of aluminum is sitting on a hot plate. A student accidentally left the hot plate on. The aluminum now is very hot and has to be cooled. You fill a
beaker with 250 grams of water. The aluminum is placed in the water. You are
curious so you place a thermometer in the beaker. The water warms from 22.3 C to
30.8 C. The C (aluminum) is 0.900 J/gc, and the C (water) is 4.18 J/gC
