Detailed explanation-1: -The kinetic theory of matter states that all matter consists of particles in constant motion. Particles of matter are attracted to each other, so they tend to pull together. The particles can move apart only if they have enough kinetic energy to overcome this force of attraction.
Detailed explanation-2: -Gases are composed of a large number of particles that behave like hard, spherical objects in a state of constant, random motion. These particles move in a straight line until they collide with another particle or the walls of the container.
Detailed explanation-3: -1. A gas consists of molecules in constant random motion. 2. Gas molecules influence each other only by collision; they exert no other forces on each other.
Detailed explanation-4: -The kinetic theory describes a gas as a large number of submicroscopic particles (atoms or molecules), all of which are in constant, random motion. The rapidly moving particles constantly collide with each other and with the walls of the container.
