Question

According to the kinetic molecular theory, which
statement describes the particles in a sample of an
ideal gas?
A. The particles are constantly moving in circular
paths.
B. The particles collide, decreasing the total energy
of the system.
C. The particles have attractive forces between them
D. The particles are considered to have negligible
volume.

Answer 1

Answer:

D. The particles are considered to have negligible volume.

Explanation:

According to the Kinetic Molecular Theory for ideal gases

- Gases are composed of larges molecules which are in constant random motion in a straight line

- The volume of the gas particles is negligible compared to the total volume in which the gas is contained.

- The attractive and repulsive forces between gas molecules is insignificant ie There are no interactive forces.

- The collisions of the particles  are perfectly elastic and energy is being transferred between the particles but the total energy remaining constant
