normal
The gas equation $\frac{{PV}}{T} = $constant, is true for a constant mass of an ideal gas undergoing
A
Isothermal change
B
Adiabatic change
C
Isobaric change
D
Any type of change
Solution
As per ideal gas equation,
$P V=n R T$
$\frac{P V}{T}=n R$
$R$ is the universal gas constant.
$n$ is the moles.
If mass is constant, then we. of moles will be constant.
So, The product $(nR)$ will be constant.
Thus, the equation is true for a constant mass of an ideal gas undergoing any type of change.
Correct choice – option – $D$
