Question

Think critically: the different molecules that make up the air in a room have, on average, the same kinetic energy. how does the speed of the different air molecules depend on their masses? your answer

Answer 1

At a given temperature, the average kinetic energy of air molecules remains the same, regardless of their mass. However, the speed of the molecules depends on their masses, with lighter molecules having a higher RMS velocity and heavier molecules having a lower RMS velocity.

Step-by-step explanation:

At a given temperature, all gases have the same average kinetic energy per molecule, regardless of their mass. However, the speed of the air molecules does depend on their masses. Lighter molecules will have more high-speed particles and a higher root mean square (RMS) velocity, while heavier molecules will have more low-speed particles and a lower RMS velocity.

Answer 2

The speed of the molecules are contingent on their masses. This is for the reason that if the the molecules are big in size, therefore their speed is slower. When their sized small, therefore their speed is faster because the molecules can move faster.
