Moderate

For a given mass of gas, if the pressure is reduced to half and its temperature is doubled, then volume V will become?

Correct answer: A. 4V

  • A. 4V
  • B. 2V2
  • C. V/4
  • D. 8V

Explanation

According to the formula PV=nRT, The pressure becomes p/2 and the temperature becomes 2T. Therefore the increase in volume will be 4V.

About Ideal Gas Equation

The ideal gas equation, PV = nRT, relates pressure, volume, amount and absolute temperature when gas particles are assumed to have negligible volume and no intermolecular forces. Applications include finding molar mass, density or an unknown gas variable, with careful use of Kelvin temperature and consistent units, and comparison with real-gas behaviour.
