B. As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy.
Explanation:
The best statement that describes the collision of gas particles according to the kinetic-molecular theory is that as particles travel in straight lines, their paths sometimes meet and then they bounce apart with no gain or loss of energy.
- The kinetic molecular theory is used to explain the forces between molecules and their energy.
One of the postulate suggests that, when molecules collide with each other, or with the wall of the container, there is no loss or gain of energy.
- Molecules are independent of one another and that forces of attraction and repulsion between molecules are negligible.
