Concept:The kinetic theory of gases describes the motion and collisions of gas molecules.
Explanation:Gas molecules are always in constant, random motion.
They move at different speeds, not a single uniform speed.
The temperature of a gas is a measure of the average kinetic energy of its molecules.
In an ideal gas, collisions between molecules are perfectly elastic, meaning total kinetic energy is conserved.
Therefore, saying that collisions are perfectly inelastic is incorrect.
Answer:D. The collision between the gases is perfectly inelastic.
