Question

which statement best describes the collisions of gas particles according to the kinetic - molecular theory? when particles pass close enough to one another, their attractions pull them together, and then they bounce apart with no gain or loss of energy. as particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy. when particles pass close enough to one another, their attractions pull them together, and then they bounce apart with a loss of energy. as particles travel in straight lines, their paths sometimes meet, and then they bounce apart with a loss of energy.

Explanation:

According to the kinetic - molecular theory, gas particles travel in straight - line paths, and when their paths meet, they undergo elastic collisions (no gain or loss of energy). There are no intermolecular attractions considered in the ideal version of this theory for elastic collisions.

Answer:

As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy.
