The average kinetic energy of the molecules of an ideal gas is directly proportional to what?
Open in App
Solution
Kinetic energy
It is a form of energy that an object or particle has because of its motion.
Kinetic energy,
Explanation
As temperature increases, the velocity of particle increases; as the square of velocity is directly proportional to the kinetic energy of the gas, kinetic energy also increases.
So, the kinetic energy of a molecule of a gas is directly proportional to the absolute temperature of the gas.
An increase in temperature increases the speed at which the gas molecules move, i.e., increases the kinetic energy.
A decrease in temperature decreases the speed at which the gas molecules move, i.e., decreases the kinetic energy.
The kinetic energy of a molecule of a gas is directly proportional to the absolute temperature of the gas.
