Question:

In the given (V-T) diagram, what is the relation between pressure P1 and P2?

Options:

Cannot be predicted

P2 = P1

P2 > P1

P2 < P1

Correct Answer:

P2 < P1

Explanation:

PV = nRT 

⇒ V = \(\frac{nR}{P}T\)

∴ slope : \(\frac{nR}{P}\)

Slope is inversely proportional to P

As \(\theta_1\) > \(\theta_2\)

Therefore, P2 < P1
