Question

For an ideal gas, correct statement are:
A) Molecules do not occupy any space
B) No attractive force exist between the molecules
C) The gas molecules move in random, straight line motion
D) None of the mentioned​

Answer 1

Explanation:

No attractive forcr exist between the molecules

Answer 2

The correct option is B)

A molecule is a group of two or more atoms held together by attractive forces known as chemical bonds; depending on the context, the term may or may not include ions that satisfy this criterion.

A) Given that gas molecules are loosely linked and constantly in motion

B) incorrect    Isotropic property says that the various properties of a material are independent of direction hence the constant ( $\frac{1}{3}$ ) is the result of the assumption that the velocity of the molecule is the same in all three axis x, y, z.

C) correct: While unrestricted movement can have an infinitely long time, collisions only last a second.

D) correct: When a perfect gas collides, there is no change in momentum since there are no attraction or repulsive forces.
