Answer:
Volume versus temperature, because they are also directly proportional
Step-by-step explanation:
The Ideal Gas Equation is :
Evaluating the options
- V ∝ P [Incorrect, because V ∝ 1/P, and graph will be a parabola]
- V ∝ T [Correct, because V ∝ T, and graph is a straight line]
- V ∝ 1/P [Incorrect, because graph is not similar]
- V ∝ 1/T [Incorrect, because V ∝ T]
