Following represent the Maxwell distribution curve for an ideal gas at two temperature T 1 and T 2 . Which of the following option(s) are true ?

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

U mps decreases as temperature decreases

T 1 > T 2 and hence higher the temperature, sharper the curve

The fraction of molecules having speed = U mps decreases as temperature increases

Text Solution

Verified by Experts

The correct answer is:

CHECK THE SOLUTION.

(a,b,d) ∴( a ) area under the curve gives fraction of molecules and total area is constant.

U mps decreases with decrease in temperature.

T 2 is higher temperature

As seen from graph ; ∴ A, B, D
