1.	The relation between pressure exerted byan ideal gas (pideal) and observed pressure (preal) is given by the equation, Pideal = Preal+an2V2 (i) If pressure is taken in Nm−2 , number of moles in mol and volume in m3,calculate the unit of 'a'. (ii) What will be unit of 'a' when pressure is in atmosphere and volume indm3?
Answer» The relation between pressure exerted byan ideal gas $(p_{i d e a l})$ and observed pressure $(p_{r e a l})$ is given by the equation, $P_{i d e a l} = P_{r e a l} + \frac{a n^{2}}{V^{2}}$ (i) If pressure is taken in $N m^{- 2}$ , number of moles in mol and volume in $m^{3}$ ,calculate the unit of 'a'. (ii) What will be unit of 'a' when pressure is in atmosphere and volume in $d m^{3}$ ?

Answer»

The relation between pressure exerted byan ideal gas $(p_{i d e a l})$ and observed pressure $(p_{r e a l})$ is given by the equation,

$P_{i d e a l} = P_{r e a l} + \frac{a n^{2}}{V^{2}}$

(i) If pressure is taken in $N m^{- 2}$ , number of moles in mol and volume in $m^{3}$ ,calculate the unit of 'a'.

(ii) What will be unit of 'a' when pressure is in atmosphere and volume in $d m^{3}$ ?
