Gas laws are NOT applicable for which of the given relations?
Correct answer: D. Volume and external conditions
- A. Volume and temperature
- B. Volume and pressure
- C. Volume and number of moles
- D. Volume and external conditions
Explanation
All of the following given relations can be stated as ideal gas laws. Boyle's law relates Pressure to Volume (inverse relation). Charle's law relates Volume to Temperature (direct relation).Charle's law relates Volume to Temperature (direct relation). Avogadro's law relates Volume to the number of Moles (direct relation). Hence, by the rule of elimination, only one option is left i.e. volume and external conditions.

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.
