The graph below compares the motion of particles in two substances. One substance is a gas and the other is a solid.
A bar graph is shown with the title Particle Motion. The y axis title is Particle Speed. The x axis title is Substance. There are two markings on the x axis. One is marked A and the other is marked B. The bar above A is lower than the bar above B.
Which statement best describes the two substances?
a) Particles are closer together in solids so Substance B is a solid.
b) Particles are farther apart in solids so Substance A is a solid.
c) Particles are farther apart in gases so Substance B is a gas.
d) Particles are closer together in gases so Substance A is a gas.
