Which of the following statements about intermolecular distances and cohesive forces between gas is correct? They are
A
Both large
B
Both negligible
C
Constant and negligible
D
Large and negligible
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible.
Cohesive Force is negligible in case of gases.
