Question

A graph of gas pressure versus the number of particles in a container is a straight line. Which other relationship will have a similar graph?

Answer 1

B.

Step-by-step explanation:

volume versus temperature, because they are also directly proportional

Answer 2

Volume has the same relationship with the number of particles than the pressure.

You can see it in the ideal gas equation: PV = nRT

As much as V and P are proportional to n.
