In the kinetic model of an ideal gas, it is assumed that:
A. The forces between the gas and the container are zero
B. The intermolecular potential energy of the molecules of the gas is constant.
C. The kinetic energy of a given gas molecule is constant
D. The momentum of a given molecule of the gas is constant
The Attempt at a Solution
I chose D, because collisions of ideal gases are perfectly elastic, but the answer was B. I wanted to know whether this answer means that for real gases, the intermolecular potential energy is not constant. [/B]
