Except at absolute zero (the coldest temperature it is possible to reach), all molecules move. This movement is a form of kinetic energy, and the more the molecules move the more kinetic energy they have. Molecules in solids don’t move much, they just vibrate.

How do molecules move in liquids?

Liquid � In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container. The attractive forces between particles are strong enough to hold a specific volume but not strong enough to keep the molecules sliding over each other.

How do molecules move in gas?

In gases the particles move rapidly in all directions, frequently colliding with each other and the side of the container. With an increase in temperature, the particles gain kinetic energy and move faster. … In liquids, particles are quite close together and move with random motion throughout the container.
