|
decrease

None of the above

Explanation:
Detailed explanation-1: -If a given gas sample is allowed to occupy a larger volume, then the speed of the molecules does not change, but the density of the gas (number of particles per unit volume) decreases, and the average distance between the molecules increases. Hence the molecules must, on average, travel farther between collisions.
Detailed explanation-2: -The motion of the particles is increased by raising the temperature. Conversely, the motion of the particles is reduced by lowering the temperature, until, at the absolute zero (0 K), the motion of the particles ceases altogether. Because the particles are in motion, they will have kinetic energy.
