Question

According to the kinetic molecular theory, which statement describes the particles in a sample of an ideal gas?

(1) The force of attraction between the gas particles is strong.
(2) The motion of the gas particles is random and straight-line.
(3) The collisions between the gas particles cannot result in a transfer of energy between the particles.
(4) The separation between the gas particles is smaller than the size of the gas particles themselves.

Answer 1

According to the kinetic molecular theory, the motion of the gas particles is random and in a straight line. The answer is 2.

Answer 2

(2) the motion of the gas particles is random and straight-line, they cannot be influenced by outside forces, one example being a magnetic field.
