In 'General Gas Equation PV=nRT', 'n' represents the number of moles of gas.Which of the following represents the relation of 'n'?
Correct answer: B. n = N/NA
- A. n = NNA
- B. n = N/NA
- C. n = NA/N
- D. n = N + NA
Explanation
The number of moles is the number of molecules divided by Avogadro's number: n = N/NA. One mole is by definition NA = 6.022 x 10^23 molecules, so dividing a molecule count by NA converts molecules into moles.

About Thermodynamics
Thermal equilibrium and heat explain how temperature and energy transfer are related, while molar specific heats describe the heat required by a gas at constant volume or constant pressure. The first law connects heat supplied, work done and change in internal energy, with sign conventions kept distinct from temperature changes.
