What characteristic allows the scent from an air freshener to spread throughout a room?

• Gases tend to condense quickly.

• Gases are heavier than air.

• Gases tend to occupy all available volume.

• Gases are attracted to solid surfaces.

How are the pressure, volume, and temperature of gases related?

• They are independent variables.

• A change in one magnitude does not affect the others.

• They are directly related, where a change in one influences the others.

• They are inversely related, where an increase in one always causes a decrease in the others.
