Topic: Thermodynamics
The universal gas constant of a gas is the product of molecular weight of the gas and
- A. Gas constant
- B. Specific heat at constant pressure
- C. Specific heat at constant volume
- D. None of the above
Answer: A. Gas constant
Explanation: We know that, $PV=mRT$ and No. of mole (n) $=\frac{m}{M}$ so, $m=nM$. Therefore, $PV=nMRT$. Here $R=$ gas characteristic constant, $n=$ No of mole, $m=$ molecular mass, $M=$ molecular weight, $\overline{R}=$ universal gas constant. Thus, $MR=\overline{R}$.
