Assertion (A) : At constant temperature, pV vs. V plot for real gases is not straight line. Reason (R ) : At high pressure, all gases have Z gt 1 but at intermediate pressure, most gases have Z lt 1.

Assertion (A) : At constant temperature, pV vs. V plot for real gases

1.	Assertion (A) : At constant temperature, pV vs. V plot for real gases is not straight line. Reason (R ) : At high pressure, all gases have Z gt 1 but at intermediate pressure, most gases have Z lt 1.
Answer» Both A and R are TRUE and R is the correct EXPLANATION of A. Both A and R are true R is not the correct explanation of A. A is true but R is false. A is false but R is true. Solution :Correct explanation. At CONSTANT TEMPERATURE, plot of pV vs. V for REAL gases is not linear because real gases have intermolecular forces of attraction.
