Ateacher did an experiment to show the movement of particles in solids, liquids, and gases. the experimental set-up is shown below: 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? liquid = low; solid = medium; gas = high. solid = low; liquid = medium; gas = high. liquid = low; gas = medium; solid = high. gas = low; liquid = medium; solid = high.

The correct answer would be solid = low; liquid = medium; gas = high.

Matter generally exists in one out of three states: solid, liquid or gas.

Solid: The particles of solids are closely packed. They have least kinetic energy as compared to the particles of liquid and gas. They have definite shape and volume i.e. they do not change shape and volume according to the container they are put in.

Liquid: The particles of liquid are loosely packed and thus they have higher kinetic energy as compared to the particles of solid state. They have definite volume however, they can change shape according to the vessel they are stored in.

Gas: The particles of the gas have highest distance among them as compared to the other states of matter. So, they have the maximum kinetic energy as compared to that of others. Gas has no definite shape and volume.
