Question

PLEASE ANSWER ASAP:

The kinetic theory of heat states that heat is the result of the movement of particles in a system. Is this statement True or False

Answer 1

• True

Step-by-step explanation:

Heat is a kind of energy.

The kinetic theory relates the heat with the movement of the particles: the more the particles move, the larger the kinetic energy of the system. The kinetic theory states that heat is the kinetic energy of the particles, atoms or molecules, in a substance, that is transferred from a substance at higher temperature to other substance at lower temperature.

Based on that principle, the kinetic theory explains the changes of phases of the substances in terms of the motion of the particles: the hotter an object the faster the particles move, the more energetic the particles are, and they occupy more space. Thus, when a solid is heated, the particles move faster and it can pass to liquid or gaseous state.
