explain the molecular concept of thermal energy
Thermal energy is the energy that is associated with the movement of molecules. At the molecular level, thermal energy is the energy that is associated with the vibrational, rotational, and translational motion of molecules.
All molecules are in constant motion due to the heat energy they possess. The faster the molecules are moving, the higher the temperature of the substance. The energy of these molecular movements increases with temperature. When a substance is heated, the energy of the...
