According to the kinetic theory of matter, particles in a substance

  1. Have no motion
  2. Are in constant random motion ✓
  3. Move only in a straight line
  4. Have motion only at absolute zero temperature

Explanation

The kinetic theory states that all matter consists of tiny particles that never stop moving. These particles move randomly in all directions, constantly colliding with each other.

The motion increases with temperature. Hot substances have fast-moving particles, while cold substances have slower-moving particles, but the particles never completely stop.

Even in solids, particles vibrate in place. In liquids they slide past each other, and in gases they fly freely through space. This constant motion explains properties like pressure, temperature, and diffusion.
