An isolated system consists of two objects of the same mass. One object has an initial temperature of 0 °C and its specific heat is c1. The other has an initial temperature of 100°C and its specific heat is c2=5 c1. What is the equilibrium temperature of the system, assuming that no phase changes take place for either object?
