Question

deeper into kinetic molecular theory
review this graph of samples of gases at the same temperature. how does average kinetic energy compare across these gases?
he has the greatest average kinetic energy because it has the greatest average speed.
xe has the greatest average kinetic energy because it has the slowest average speed.
they all have the same average kinetic energy because theyre all at the same temperature.
xe has the greatest average kinetic energy because it has the greatest average speed.

Explanation:

According to the kinetic - molecular theory, the average kinetic energy of gas molecules is directly proportional to the temperature. Since all the gas samples are at the same temperature, they have the same average kinetic energy.

Answer:

They all have the same average kinetic energy because they're all at the same temperature.
