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

3. how much energy in joules is required to evaporate .0005 kg of liquid ammonia to vapor at the same temperature? 4. how much energy ( in megajoules ) is given up by .75 kg of water at 0c when it freezes to form ice at 0c? 5. explain how heat works between and at critical temperatures?
