Which of the following statements about intermolecular distances and cohesive forces between gas is correct? They are
Both large
Both negligible
Constant and negligible
Large and negligible
توضیح
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.
