Two 50 g metal blocks, one made of lead and the other of iron, are heated to 100°C. They are placed in identical calorimeters, each with 100 g of water at a starting temperature of 20°C. Which calorimeter will have the higher temperature at thermal equilibrium: the one with lead or the one with iron? Explain your answer.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

a.   mass number from atomic number
