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

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

Explanation:

Kinetic - molecular theory -

According to this theory , gas is considered to be as a large number of very small particles , which moves randomly , and due to this randomness collisions occurs , as the particles collide with each other and the wall of the container .

During these collisions , there is no loss or gain of energy , there is only transfer of energy .

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