Two metals, A and B are placed in direct contact in an insulated container. Metal A has a mass
of 50 g and an initial temperature of 150 °C, and metal B had a mass of 50 g and an initial
temperature of 50°C. If the equilibrium temperature of the two metals is 75°C, which metal has a
higher specific heat?
