Problem
Copper block A (mass 0.50 kg) is initially at 150 °C, block B (mass 0.30 kg) is initially at 50 °C, and block C (mass 0.20 kg) is initially at 20 °C. The three blocks are simultaneously placed together in an insulated container and allowed to reach a common equilibrium temperature. Assuming the specific heat capacity of copper is 390 J kg⁻¹ °C⁻¹ and neglecting any energy loss to the surroundings, calculate the equilibrium temperature of the system.
