NEET Physics Ideal Gas Equation MCQ Question
Which of the following statements about the ideal gas equation and molecular motion is correct?
The average kinetic energy of a gas molecule is directly proportional to the absolute temperature of the gas.
Collisions between gas molecules do not affect their velocities at all.
The volume of a gas is independent of the number of molecules present.
An increase in pressure at constant volume will decrease the average kinetic energy of the molecules.
Correct Answer
Detailed Explanation
The average kinetic energy of a molecule is proportional to the absolute temperature of the gas, as stated in the ideal gas equation and its derivation, indicating that the temperature is a measure of energy.
