Assertion: Volume of gas at 50 $^{0}$ C is V. Keeping the pressure constant, the temperature is doubled. Volume becomes 2V.
Reason: At constant pressure, the volume of gas is directly proportional its to absolute temperature.

Solution

The correct option is A Both assertion (A) and reason (R) are correct and R gives the correct explanation
Since PV=nRT
therefore, at constant P
V=nRT/P
therefore if we double T then V will also gets doubled
both assertion and reason are correct and reason is true explanation of assertion
option(A)
