Question
In the ideal gas equation $PV = nRT$, the physical significance of the universal gas constant $R$ relates to which of the following combinations of fundamental dimensions?
Answer: B
💡 Solution & Explanation
The dimensions of $R$ are derived from $R = PV/nT = (\text{Force}/\text{Area}) \times \text{Volume} / (\text{mole} \times \text{Temperature}) = (\text{Force} \times \text{Length}) / (\text{mole} \times \text{Temperature}) = \text{Work or energy} / (\text{mole} \times \text{Kelvin})$.
