Question

There is 10 litre of a gas at STP. Which of the
following changes keeps the volume constant
(A) 273 K and 2 atm (B) 273°C and 2 atm
(C) 546°C and 0.5 atm (D) 0°C and 0 atm​ (please calculate this question)

Answer 1

Answer:

Option B) 273°C and 2 atmospheric pressure.

Explanation:

Since, we know that the pressure multiplied by volume or PV is equal to nRT and from this equation we also get that the volume will be directly proportional to the pressure by time or P/T.

So, from the above explanation we can conclude that the volume remains constant when the temperature and the pressure both are doubled. Therefore from the above option only in option B the temperature is doubled as 273°C is equal to 573K and the pressure is 2 atmospheric pressure.
