Q. The relationship between pressure and the density of a gas expressed by Boyle's law, $P=K D$ holds true

Kinetic Theory Report Error

A

For any gas under any conditions

B

For some gases under any conditions

C

Only if the temperature is kept constant

D

Only if the density is constant

Solution:

At constant temperature; $P V=$ constant
$\Rightarrow P \times\left(\frac{m}{D}\right)=\text { constant } $
$\Rightarrow \frac{P}{D}=\text { constant }=K .[D=\text { Density }]$
