A student describes the motion of particles in each of the four different states of matter.

State 1: Particles that are charged move freely
State 2: Particles move freely at high speed
State 3: Particles are locked in place
State 4: Particles slide past one another

Which state describes solids?

The state that describes solids is State 3: Particles are locked in place. In solids, particles are tightly packed and held in fixed positions, which gives solids a definite shape and volume.
