Chemical Engineering Thermodynamics

Keeping the pressure constant, to double the volume of a given mass of an ideal gas at 27°C, the temperature should be raised to __________ °C.

  • A. 270
  • B. 327
  • C. 300
  • D. 540
Answer: Option B.

For an ideal gas PV = nRT
So, at constant pressure volume is directly proportional to temperature so to double the volume the temperature also has to be doubled, so the temperature has to be 327∘C.
