Question

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`.
A. Both A and R are true and R is the correct explanation of A.
B. Both A and R are true R is not the correct explanation of A.
C. A is true but R is false.
D. A is false but R is true.

Answer 1

Correct Answer - B
Correct explanation. At constant temperature, plot of pV vs. V for real gases is not linear because real gases have intermolecular forces of attraction.
