Question

molecular motion is a measure of the movement of the molecules in a substance. molecular motion is substantially different between the different states of matter. for example, the molecules in

a. air, wood

b. wood, air

c. soda, air

d. wood, soda

move more than the molecules in

Explanation:

Molecular motion varies with the state of matter. In gases (like air), molecules have high kinetic energy and move freely. In liquids (like soda), molecules have moderate motion. In solids (like wood), molecules have limited motion. So, comparing air (gas) and wood (solid), air molecules move more.

Answer:

C. soda, air
