Question

How are particle movements and thermal energy related?

Answer 1

Particle movements and thermal energy are related because thermal energy refers to the kinetic energy of particles in a substance due to their random motion. As particles move, they collide with each other and transfer energy, which leads to an increase in their average kinetic energy and temperature. Thus, the more particle movement and collisions there are, the higher the thermal energy and temperature of the substance. In other words, particle movements contribute to the thermal energy of a system.
