Question

How does the kinetic energy of a substance's particles in the gas phase compare to their kinetic energy in the solid phase?

A. The kinetic energy of the solid and liquid phases is the same.
B. The kinetic energy of the substance's particles will depend on the volume of the substance.
C. The particles have less kinetic energy in the gas phase than in the solid phase. D. The particles have more kinetic energy in the gas phase than in the solid phase.

Answer 1

answer is d. gas has more kinetic energy than liquid and liquid more than solid

Answer 2

Answer: Option (D) is the correct answer.

Step-by-step explanation:

In solids, the particles are held together by strong intermolecular forces of attraction. As a result, there is very less or no kinetic energy between the particles.

Therefore, solids are rigid and have definite shape and volume.

Whereas in gases, the particles are held by weak Vander waal forces. As a result, the particles collide with each other and gains kinetic energy.

Thus, we can conclude that the particles have more kinetic energy in the gas phase than in the solid phase.
