Question

One mole of an ideal gas undergoes a process `P = (P_0)/(1+(V/V_0)^2` where `p_0` and `V_0` are constants . Find the temperature of the gas when `V=V_0` .

Solution

Given : 

`P = (p_0)/(1+(V/V_0)^2`

Multiplying both sides by V, we get

`pV = (p_0V)/(1+(V/V_0)^2)`

`pV = RT`              [From eq. (1)]        

Now , 

`RT = (p_0V)/(1+(V/V_0)^2)`

`T = 1/R ((p_0V_0)/(1+(V_0/V_0)^2))`       [`V=V_0`]

⇒ `T = (p_0V_0)/(2R)`
