Thermal Energy Applied to Chemistry:

Thermal energy is directly related to the motion of particles in a substance. The

the particles move, the more thermal energy they have. This is because thermal energy is the total kinetic energy of all particles in a substance. So, when the particles move faster, they have more kinetic
