Following represents the Maxwell distribution curve for an ideal gas at two temperature `T_(1)` and `T_(2)` . Which of the following option(s) is/are true?

A

Total area under the two curves is independent to moles of gas

B

`u_(mp)` decrease as temperature decreases

C

`T_(1)gtT_(2)` and hence higher the temperature, sharper the curve

D

The fraction of molecules having speed `u_(mp)` decreases as temperature increases

Text Solution

Verified by Experts

The correct Answer is:
a,b,d
(a,b,d) (A) `:'` area under the curve gives fraction of molecules and total area is constant.
(B) `u_(mp)` decreases with decrease in temperature.
(C) `T_(2)` is higher temperature
(D) As seen from graph, `:.` A,B,D
