A sample of O_(2) gas initially at NTP is transferred from a 1-litre container to a 2-litre container at a constant temperature. What effect does this change have on (a) the average kinetic energy of O_(2) molecules (b) the average speed of O_(2) molecules (c) the rms speed of O_(2) molecules (d) the total number of collisions of O_(2) molecules with the container waals in a unit time.

1.	A sample of O_(2) gas initially at NTP is transferred from a 1-litre container to a 2-litre container at a constant temperature. What effect does this change have on (a) the average kinetic energy of O_(2) molecules (b) the average speed of O_(2) molecules (c) the rms speed of O_(2) molecules (d) the total number of collisions of O_(2) molecules with the container waals in a unit time.
Answer» SOLUTION :(a) No change in average kinetic energy as the temperature remains constant. (b) & (c) No change in average speed and RMS speed as the average kinetic energy remains unchanged. (d) Number of collisions per unit time with the CONTAINER walls decrease, as due to increase in volume, the MOLECULES move longer distances between collisions.
