In order to fnd the specifc heat c of an unknown substance, you place 75 g of the substance in a 30 g copper calorimeter that contains 65 g of water, all initially at 20 °C. You then add 100 g of water at 80 °C, and measure the fnal temperature of the system to be 49 °C. Assuming no heat is lost to the environment, what is c? [Answer: c = 2200 J/kg. K]
