A Copper Cylinder with a Mass of 125 G and Temperature

question 38

Short Answer

A copper cylinder with a mass of 125 g and temperature of 345°C is cooled by dropping it into a glass beaker containing 565 g of water initially at 20.0°C.The mass of the beaker is 50.0 g and the specific heat of the glass is 840 J/kg • K.What is the final equilibrium temperature of the system,assuming the cooling takes place very quickly,so that no energy is lost to the air? The specific heat of copper is 385 J/kg • K and that of water is 4190 J/kg • K.
