7. Heat is (a) a fluid called caloric. (b) a measure of the average kinetic energy of atoms. (c) the amount of energy transferred between objects as a result of a difference in temperature. (d) an invisible, odorless, weightless substance. (e) the total kinetic energy of an ideal gas. Solution When two materials are at different temperatures (that is, they have different average kinetic energies per molecule), energy can transfer from the hot object to the cold object. This transfer of energy is called heat.Heat is not a propety of material neither its a matter. Heat is (c) the amount of energy transierred between objects as a result of a difference in temperature . .
