Kinetic energy of gas molecules is directly proportional to-

Correct option is D

The correct answer is (d) Temperature.
· The kinetic energy of gas molecules is directly proportional to the temperature of the gas. This relationship is described by the kinetic theory of gases, which states that the average kinetic energy of gas molecules is proportional to the absolute temperature.
· As the temperature of a gas increases, the molecules move faster, thereby increasing their kinetic energy.
Information Booster:
· Atmospheric pressure: The pressure exerted by the weight of the atmosphere above the surface of the earth, it does not directly affect the kinetic energy of gas molecules.
· Pressure: While gas pressure can influence the behavior of gases (according to the ideal gas law), it is not directly proportional to the kinetic energy of the molecules.
· Both temperature and pressure: This combination affects the state of the gas but the kinetic energy is directly related only to temperature.
