Particle Motion of Solids

  • There are two basic types of particle arrangement in solids. Click here to find out more.

The particles in solids don’t move much, but they do vibrate in place slightly.

Notice how the solid maintains its shape in the container.

What happens to particles in an object if you heat it?

The particles move faster, pushing further apart. This means the whole object expands. After some time, the particles will be forced to change state. e.g. Solid to liquid.

THE PARTICLES THEMSELVES DO NOT EXPAND!

Two forms of Energy:

​

1. Potential Energy

- stored energy

Potential energy is stored energy due to the interactions between particles or objects. The potential energy increases as the distance between particles increases.

​

Otherwise, the potential energy decreases as the distance between the particles decreases. The particles that are farther apart have more potential energy. The potential energy of the particles, determined by the state of matter present, contributes to the total energy of a substance.
