Q.What would be the SI unit for the quantity pV2T 2/n?
The SI unit of the given quantity is obtained by substituting the SI units of all the quantities in its expression.
The SI unit for pressure, p is Nm–2.
The SI unit for volume, V is m3.
The SI unit for temperature, T is K.
The SI unit for the number of moles, n is mol.
Therefore, the SI unit for quantity pV2T2 / n is given by substituting the above values in the given expression
pV2T2 / n = (Nm-2) x (m3)2 x K2 / mol
= Nm4K2 mol-1
