Why would you not expect all the molecules of air in your room to have the same average speed?

Answer 1

The average speed of a gas molecule is determined by two factors, its temperature and molecular mass.

Oxygen molecules at the same temperature will have the same average speed. Air, however, is made up of several types of gas molecules (nitrogen, oxygen, carbon dioxide, etc.). Each type of gas molecule in air of the same temperature will have a different average speed because each has a different molecular mass.

Answer 2

It does not violate any physical laws, there is nothing in physics that prevents all the molecules in the room from having the same velocty and rushing toward the ceiling at the same time. It just has an extremely low probability of happening.

Answer 3

No. Clarifying your question, different kinds of molecules like nitrogen (N2) and oxygen (O2) would not have different averages speeds, even if the temperature and pressure were in equilibrium (no candles, drafts, etc.) because there molecular masses are different. They would, instead, have the same average kinetic energy in the ideal gas approximation.

Answer 4

The difference in heat caused the molecules to move at different speeds the hotter it is in one spot has molecules moving faster.

Answer 5

what jimbo said plus that fact that air is made of different molecules having different weights. the bigger molecules would naturally move slower than the smaller ones

Answer 6

this is thoroughly elective to deliver your AP scores, however might desire to faculties will ask you to checklist your rankings. the single time that your AP Chem test might essentially quite matter might desire to be once you're making plans to be a technological expertise foremost, even though if a minimum of you tried. in case you dont take the class in any respect you dont have an AP score to cutting-edge. Take a deep breath, attempt to appreciate it and once you in undemanding terms can not get it, its now not the precise of the international. severe college is basically the putting out of your academic journey, blunders take place and probably this might an increasing style of basically be a get up call that possibly Chemistry basically isn't your super self-discipline, each physique has their weaknesses. for people who income information of to settle for them and triumph over them, you would be set.

Answer 7

Even discounting variations in temperature, the Brownian motion of molecules would assure variations.

Answer 8

Also, they have different masses. So, even if they are all at the same temperature, because their masses are different, their speeds will differ.

Answer 9

entropy
