Question

a) The average kinetic energy of the oxygen molecules is determined only by temperature. the average kinetic energy is not changed by the compression of O2 at constant temperature.

b) If the average kinetic energy of O2 molecules doesn't change, the average speed remains constant.

c) As the molecules are moving within a samller volume but with the same average speed as before, so under these conditions they will collide with the wall of the container so that the total number of collisions with the container walls in a unit time will increase.

d) The number of collisions with a unit area of wall increases because the total number of collisions with the walls is higher and the area of wall is smaller than before.

e) Increase in pressure is proportional to the number of collisions. So the pressure will increase.

Explanation / Answer

16. A sample of o, gas initially at STP is compressed to a smaller volume at constant temperature. What effect does this change have on (A) the average kinetic energy of the molecules, (B) their average speed, (C) the number of collisions they make with the container walls per unit time, (D) the number of collisions they make with a unit area of container wall per unit tim (E) the pressure?
