Question

The volume vs. temperature graph of 1 mole of an ideal gas is given below. The pressure of the gas (in atm) at X,Y and Z, respectively, are

• A. 0.328,0.820,0.820
• B. 3.28,8.20,3.28
• C. 0.238, 0.280, 0.280
• D. 32.8, 0.280, 82.0

Answer 1

The correct option is A

0.328,0.820,0.820

Using ideal gas equation, PV = nRT

$P=\frac{nRT}{V};P_x=\frac{1\times 0.082\times 200}{50}=0.32atm{P}_y=\frac{1\times 0.082\times 500}{50}=0.820atm{P}_z=\frac{1\times 0.082\times 200}{50}=0.820atm$
