Problem 22E

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

Step-by-Step Solution:

Solution 22E Step 1 of 2 : The air molecules in the room have same Kinetic energy but not the same average speed. Since air is made up of different kind of gases, like nitrogen oxygen and small amount of other gases.As the molecules of the different gas have different mass. They possess different average speeds to maintain equal kinetic energy. That is, The average kinetic energy of the atoms in a mixed gas in room at same temperature will be equal(from gas laws). KE= mv1 2 2 Where KE is the kinetic energy, m is the mass of atom and v is the speed of atom. Since for air is a mixture of gas with same temperature, KE = KE 1 2
