Boltzman constant K in terms of universal gas constant R and Avagadros number Na is give as_______________?
Correct answer: B. K = R/Na
- A. K = RNa
- B. K = R/Na
- C. K = Na/Ra
- D. K = nRNa
Explanation
Boltzmann's constant is the gas constant per molecule, so k = R/Na. For example, R has units J mol^-1 K^-1 and Na has units mol^-1, giving k in J K^-1; the likely mistake is choosing RNa, which multiplies instead of divides by the number of molecules per mole.

About Molar Specific Heat of a Gas
Molar specific heat is the heat required to raise the temperature of one mole of a gas by one kelvin, expressed through Q = nCΔT. Questions compare the constant volume value Cv with the constant pressure value Cp, apply the ideal gas relation Cp − Cv = R, and identify how the thermodynamic process affects heat capacity.
