Which of the following is true of gases?

Gases are not easily compressed because of expansion and limited space between particles.

Gases mix easily because of their high kinetic energy and low intermolecular forces.

Gas particles diffuse easily because of their low fluidity and high intermolecular forces.

Gas particles spread out to fill a container because of their high density and high kinetic energy.

The correct answer is "Gases mix easily because of their high kinetic energy and low intermolecular forces."

Explanation:

Gases are compressed easily, gas particle don't diffuse easily, and gas has low density.

Answer;

Gases mix easily because of their high kinetic energy and low inter-molecular forces.

Explanation; Gases have no definite shape or volume, they fill or take the shape of their container. They have low density since the particles are far apart and almost empty space. Gases particles easily slide past each other and are easily compressed because of the space between the particles They also mix easily because of continuous motion, that results from high kinetic energy of particles and low inter-molecular spaces.
