Question

Which of the following correctly describes an assumption made by the kinetic molecular theory?
Answer

Gas particles exert slight attractive and repulsive forces between each other.

During collisions between gas particles, a small amount of kinetic energy is lost.

The motion of one particle of gas is independent of the motion of other particles.

Gas pressure is the result of a loss of kinetic energy between gas molecules.

Answer 1

In an ideal situation, kinetic molecular theory suggests that a gas consists of a collection of small particles traveling in "straight-line motion. And the collisions of the gas particles and the walls of the contains are perfectly elastic, meaning no energy is lost or gained during the collision. So you can cross B out.

Answer 2

According to kinetic molecular theory, there are no attractive or repulsive forces between the molecules. so you can cross A out.

Answer 3

C is true.
The motion of one particle of gas is independent of the motion of other particles.

Answer 4

and last is opposite. pressure is the result of a gain of kinetic energy between gas molecules. just think of a container that contains gas, when you increase the temperature, the pressure of the gas inside the container will also increase.

P=T/V, where pressure is directly proportional to temperature, meaning if you increase the temperature, the pressure will also increase. And V is inversely proportional to P, meaning if you increase the pressure at a constant temperature, the volume will decrease.

Answer 5

to half.
