Specific heats can be measured in a drop calorimeter in which a heated sample is dropped into the calorimeter and the final temperature is measured. When 40.0 g of a certain metal at 75.0 oC is added to 25.0 g of water (with Cp=4.184 J/[g oC]) at 10.0 oC in an insulated container, the final temperature is 20.0 oC.
