Which of the following graphs correctly represents the variation β β = - d V d P T / V of with P for an ideal gas at constant temperature?

Correct answer

0

Step-by-step solution

As P V = R T So P   ×   dV   +   V   ×   dP   =   0 or d V d P r = V P or β = d V d P r V = 1 P Hence, Plot in (A) is correct.
