Question

Value of gas constant $R$ in the ideal gas equation $PV=nRT$ depends upon:

• A. temperature of the gas
• B. pressure of the gas
• C. units in the $P,V$ and $T$ are measured
• D. nature of the gas

Answer 1

The correct option is C units in the $P,V$ and $T$ are measured

$R$ is universal gas constant

It is has fixed value which would depend upon the units in which $P,V$ and $T$ expressed in the equation $PV=nRT$

$R=\frac{PV}{nT}$
