1. The problem statement, all variables and given/known data 50 grams of brass shot are heated to 200C° and dropped into a 50-g aluminum cup containing 160-g of water. The temperature of the cup and water are 20 C°. what is the equilibrium temperature. 2. Relevant equations mcΔT=mcΔT 3. The attempt at a solution I've made a few different attempts but all of them are horribly wrong and long. If any one can drop a hint or a formula to work off that would be awesome.
