Which one is the form of general gas equation?
Correct answer: A. PV = nRT
- A. PV = nRT
- B. PV = RT
- C. P1 V1 / T1 = P2 V2 / T2
- D. All of these
Explanation
The general gas equation, or combined gas law, relates the pressure, volume, and temperature of a fixed amount of gas. It is expressed as PV = nRT.

About Gases
Gas behaviour is explained through the kinetic molecular theory and the relationships among pressure, volume and temperature. Work includes STP, Boyle's and Charles's laws, absolute zero, the ideal gas equation, and the distinction between ideal and real gases, especially the effects of intermolecular forces and molecular volume.
