Assertion (A): Volume of gas at 50°C is ‘V’. Keeping the pressure constant, the temperature is doubled. Volume becomes 2V.
Reason (R): At constant pressure, the volume of gas is directly proportional to its absolute temperature.

  Both assertion (A) and reason (R) are correct and R gives the correct explanation

• B

  Both assertion (A) and reason (R) are correct but R does not give the correct explanation

• C

  A is true but R is false
