Behaviour of Real Gases
CHXI06:STATES OF MATTER

314068 Assertion :
At constant temperature, PV vs V plot for real gases is not a straight line.
Reason :
At high pressure, all gases have \(\mathrm{Z>1}\) but at intermediate pressure most gases have \(\mathrm{\mathrm{Z}}\) \(\mathrm{ < 1}\).

1 If both Assertion & Reason are true and the reason is the correct explanation of the assertion.
2 If both Assertion & Reason are true but the reason is not the correct explanation of the assertion.
3 If Assertion is true but Reason is false.
4 If both Assertion is true but Reason is false.
