A teacher did an experiment to show the movement of particles in solids, liquids, and gases. The experimental set-up is shown below: A glass box is shown. Small spheres are shown inside the box taking up half of the space in the box. A blow dryer is shown with its mouth fitted inside a circular hole on the middle of the top surface of the glass box.

The dryer speed can be adjusted at low, medium, and high to represent each state of matter. Which combination of the state of matter and the corresponding dryer speed is correct? (5 points)

a
liquid = low; solid = medium; gas = high.

b
solid = low; liquid = medium; gas = high.

c
liquid = low; gas = medium; solid = high.

d
gas = low; liquid = medium; solid = high.
