Which property of gases is explained by the process of diffusion?

a.
their ability to compress under high temperature
b.
their ability to expand under low temperature
c.
their ability to expand under pressure
d.
their ability to fill the available volume of a container

their ability to fill the available volume of a container

Explanation:

Diffusion is the movement of gas molecules from a region of higher concentration to a region of lower concentration. Gasses fill up the volume of a container because gas molecules spread out in empty space. By so doing they fill up the volume of the container. This spreading out is caused by diffusion. Hence this property is explainable by diffusion.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
