Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A) : An ideal gas is enclosed within a container fitted with a piston. When volume of this enclosed gas is increased at constant temperature. The pressure exterted by gas on piston decreases. Reason (R) : In the above situation, the rate of molecuels per unit area striking on the piston decreases. In t
Options
- ABoth (A) and (R) are true and (R) is the correct explanation of (A).
- BBoth (A) and (R) are true and (R) is NOT the correct explanation of (A).
- C(A) is true but (R) is false.
- D(A) is false but (R) is true.
Correct answer
A. Both (A) and (R) are true and (R) is the correct explanation of (A).
Step-by-step solution
As ( p = RT Mw p = ( M V ) ( RT Mw ) ) at constant temperature ( p 1 ~V ) ( V ) and ( P )
