Assertion : Blue star is at high temperature than red star.
Reason : Wein's displacement law states that `T prop (1//lambda_(m))`.

A

If both Assertion and Reason are correct but Reason is the correct explanation of Assertion.

B

If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.

C

If Assertion is true but Reason is false

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
`T alpha 1/(lambda_(m))` alpha f rArr` As `f_(blue) gt f_(red)`. So, blue stars are hotter.

Following figure shows on adiabatic cylindrical container of volume V_(0) divided by an adiabatic smooth piston (area of cross-section = A ) in two equal parts. An ideal gas (C_(p)//C_(y)=lambda) is at pressure P_1 and temperature T_1 in left part and gas at pressure P_2 and temperature T_2 in right part. The piston is slowly displaced and released at a position where it can stay in equilibrium. The final pressure of the two parts will be (Suppose x = displacement of the piston)

Assertion: If H_(2) and Cl enclosed separately in the same vessel exert pressure of 100 and 200 mm respectively, their mixture in the same vessel at the same temperature will exert a pressure of 300 mm Reason: Dalton's law of partial pressures states that total pressure is the sum of partial pressures.
