Solution

The correct option is E heated to a higher temperature
According to the Kinetic-Molecular Theory, the kinetic energy of the molecules increases when they are heated to a higher temperature.
The kinetic energy is directly proportional to the absolute temperature.
Kinetic energy $\propto$ absolute temperature.
As temperature increases, kinetic energy increases.
As temperature decreases, kinetic energy decreases.

Q. When a system absorbs heat,the molecules start moving faster because kinetic energy increases,hence disorder increases. For the same amount of heat absorbed at lower temperature,the disorder is more than at higher temperature.why?explain.

Q. At ordinary temperatures, the molecules of a diatomic gas have only translational and rotational kinetic energies. At high temperatures, they may also have vibrational energy. As a result of this compared to lower temperatures, a diatomic gas at higher temperatures will have-

Q. Statement 1: According to the Kinetic Moecular Theory, the particles of a gas are in random motion at absolute zero temperature.
Statement 2: The degree of random motion of gas molecules varies inversely with the temperature of the gas.
