Solids, liquids and gases — practice question

The diagrams illustrate how particles are arranged in three different states of matter. Which row describes how the particles’ energy and particle motion change for the stated change of state?

  • Achange in state $1 \rightarrow 2$, energy of particles decreases, particle motion decreases
  • Bchange in state $2 \rightarrow 1$, energy of particles decreases, particle motion increases
  • Cchange in state $3 \rightarrow 1$, energy of particles increases, particle motion increases
  • Dchange in state $1 \rightarrow 3$, energy of particles increases, particle motion decreases
