Question

# If all other conditions remain constant, then select the pair of variables are inversely proportional to one another for a gas?

- P, V
- P, T
- V,P
- n, V

## The correct answer is: P, V

### According to the Ideal Gas Equation,

PV = nRT

Considering P constant,

V ∝ T

Considering V constant,

P ∝ T

Considering T constant,

P ∝ 1/V

Hence, P and V are inversely proportional.
