Which of the following is not correct regarding gases?
Which of the following is not correct regarding gases?
The correct option is C C) Gases have very weak tendency to diffuse
Explanation for correct answer:
C) Gases have very weak tendency to diffuse
Gases particles are very loosely packed because of weak intermolecular force between the particles . Hence, they diffuse very fast.
Explanation for incorrect answers:
A) Gases exert pressure
The pressure exerted by gas is due to the random motion of particles in the gas. They have weak intermolecular forces and the particles are in continuous random motion due to which these particles collide with the walls of the container and such collisions exert pressure on the gas.
B) Gases are more compressible than liquids.
Gases are compressible because most of the volume of gas is composed of the large amount of empty space between the gas particles.
D) Gases have weak intermolecular forces of attraction
The average kinetic energy of the particles in a gas is great enough to overcome the forces of attraction between them. Hence, the intermolecular forces of attraction are weak.
Hence, option C) is the correct answer as it is the only property that is not present in gases.
