Following statements are given:
(A) The average kinetic energy of a gas molecule
decreases when the temperature is reduced.
(B) The average kinetic energy of a gas molecule
increases with increase in pressure at constant
temperature.
(C) The average kinetic energy of a gas molecule
decreases with increase in volume.
(D) Pressure of a gas increases with increase in
temperature at constant pressure.
(E) The volume of gas decreases with increase in
temperature.
Choose the correct answer from the options given
below:
(A) The average kinetic energy of a gas molecule
decreases when the temperature is reduced.
(B) The average kinetic energy of a gas molecule
increases with increase in pressure at constant
temperature.
(C) The average kinetic energy of a gas molecule
decreases with increase in volume.
(D) Pressure of a gas increases with increase in

(E) The volume of gas decreases with increase in
temperature.
Choose the correct answer from the options given
below:
View answer and explanation
Correct option: A
(A) only
Option A ((A) only) is correct because the average kinetic energy of a gas molecule is directly proportional to temperature.
