alleryThe ideal gas equation of state is:
A$PV = RT$
B$PV = nRT$
C$P + V = nRT$
D$\dfrac{P}{V} = nRT$
Answer & Solution
Correct answer: B. $PV = nRT$
Ideal gas law: $PV = nRT$, where $P$ is pressure, $V$ is volume, $n$ is moles, $R$ is the universal gas constant ($8.314$ J/(mol·K) or $0.0821$ L·atm/(mol·K)), and $T$ is absolute temperature in Kelvin.
This equation combines Boyle's law ($PV =$ const at fixed $T, n$), Charles's law ($V/T =$ const at fixed $P, n$), and Avogadro's hypothesis ($V/n =$ const at fixed $T, P$) into one statement.
