Explanation
We know, ideal gas equation,
PV = nRT
Here T = constant.
$$ \therefore $$ PV = constant
$$ \Rightarrow $$ P $${m \over \rho }$$ = constant
$$ \Rightarrow $$ P $$ \propto $$ $$\rho $$
PV = nRT
Here T = constant.
$$ \therefore $$ PV = constant
$$ \Rightarrow $$ P $${m \over \rho }$$ = constant
$$ \Rightarrow $$ P $$ \propto $$ $$\rho $$
