To determine the specific heat of a new metal alloy, 0.150 kg of the substance is heated to 400oC and then placed in a 0.200-kg aluminum calorimeter cup containing 0.400 kg of water at 10.0oC. If the final temperature of the mixture is 30.5oC, what is the specific heat of the alloy? (Ignore the calorimeter stirrer and thermometer.)
