Sketch shows the plot of Zvsp for a hypothetical gas for one mole at
three distinct temperature
Boyle’s temperature is the temperature at which a gas shows ideal behaviour over a pressure range in the low pressure region. Boyle’s temperature 
. If a plot is obtained at temperature below Boyle’s temperature then the curve will show negative deviation in low pressure region and positive deviation in the high pressure region. Near critical temperature, the curve is more likely as 
and the temperature above critical temperature curve is more like
at 
For 500 K plot value of 
changes from 2 to 2.2 if pressure is varied from 1000 atm to 1200 atm (high pressure) then the value of 
will be
The correct answer is:
We know that
In the high pressure region
…(i)
…(ii)
Solving both the equation we get
