One way of expressing the equation of state for an ideal gas is by the equation pV = NkT. What do 'N' and 'K' represent respectively
Correct answer: C. Total number of molecules; Boltzmann constant
- A. Avogadro constant; Boltzmann constant
- B. Avogadro constant; Molar gas constant
- C. Total number of molecules; Boltzmann constant
- D. Total number of molecules; Avogadro constant
Explanation
In the ideal gas equation pV = NkT, 'N' represents the total number of molecules of gas, while 'k' represents the Boltzmann constant. The other options are incorrect because 'N' does not represent Avogadro's constant or the molar gas constant, and 'k' is not the Avogadro constant.

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.
