Accepted Answer

Gas particles are in constant, random motion.

Answer

Gas particles lose energy after collisions.

Answer

Gas particles move in a predictable pattern.

Answer

Question 25

How does the kinetic molecular theory explain the diffusion of gases?

Accepted Answer

Gas particles move randomly and spread out to fill the available space.

Answer

Gas particles move in a straight line until they hit a barrier.

Answer

Gas particles are attracted to each other, causing them to spread.

Answer

Gas particles are too heavy to move, preventing diffusion.
