Question

Choose the correct option for graphical representation of Boyle's law, which shows a graph of pressure vs. volume of a gas at different temperatures :

• A.
  
  
• B.
  
• C.
  
• D.
  

Answer 1

The correct option is A



According to Boyle's law,

The Pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.

$P\propto \frac{1}{V}\Rightarrow P=\frac{k}{V}\Rightarrow PV=k$
where $k$ is proportionality constant and equal to nRT.

$\therefore$ Graph between $Pvs$. $V$ should be rectangular hyperbola and product of PV increases with increase in temperature.
$\Rightarrow$ Correct Answer is option (a) .
