Choose the correct statement below regarding heat and temperature. When a hot object is placed in contact with a cold object, it loses heat until it reaches the temperature of that cold object. Heat is energy that is transferred between objects. The temperature of an object is related to its kinetic energy - increasing the temperature increases the mass in the kinetic energy equation. Only kinetic energy can be transformed into heat energy.
