# Problem: A coffee-cup calorimeter contains 150.0 g of water at 25.2 oC . A 123.0-g block of copper metal is heated to 100.4 oC by putting it in a beaker of boiling water. The specific heat of Cu(s) is 0.385 J/g. The Cu is added to the calorimeter, and after a time the contents of the cup reach a constant temperature of 30.2 oC .What would be the final temperature of the system if all the heat lost by the copper block were absorbed by the water in the calorimeter?
