The particles in a liquid are further apart than in a solid.

The particles in a solid are further apart than those in a liquid.

Sand is soluble in water.

When wax melts, particles are lost.

Water boils at 100 degrees celsius

When something moves directly between a solid and a gas, it is called subliming.
