What is average speed (barc or u_(av)) ?

1.	What is average speed (barc or u_(av)) ?
Answer» Solution :It is the arithmatic mean of the SPEED of different MOLECULES of the gas at a given TEMPERATURE if `n_(1)` molecules have speed `v_(1),n_(2)` molecules have speed `v_(2)n_(2)` molecules have speed `V_(3)` and so on. Average speed is related to the molar mass (M) of the gas the temperature (T) as follows. `barC (or U_(av))= sqrt((8RT)/(pi M))`
