A gas in a container A is in thermal equilibrium with anothergas of the same mass in container B. If the corresponding pressures and volumes are denoted by suffixes A and B, then which of the following statements is true ?

A

$$P_A$$ ≠ $$P_B$$; $$V_A = V_B$$

B

$$P_A = P_B$$; $$V_A$$ ≠ $$V_B$$

C

$$\frac{P_A}{V_A} = \frac{P_B}{V_B}$$

D

$$P_AV_A = P_BV_B$$
