Based on boyle's law, which of the following statements is true for an ideal gas at a constant temperature and mole amount?

a) pressure is directly proportional to volume.
b) pressure is inversely proportional to volume.
c) the number of collisions is independent of pressure.
d) the number of collisions decreases with increase in pressure.

B) Pressure is inversely proportional to volume.

Explanation:

B) Pressure is inversely proportional to volume.

Explanation:

The simplest way to think about it is as volume goes up, pressure goes down.

This is because gases expand to fit their container, and pressure would be the density, or amount of particles in a volume. If you have gas in a container, and you expand the container, the pressure will decrease as the volume increases.
