Q. The relationship between pressure and the density of a gas expressed by Boyle’s law, $P = KD$ holds true
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
Explanation
(c) At constant temperature; $PV =$ constant
$\Rightarrow P \times \left( \frac{m}{D} \right) = constant$
$\Rightarrow \frac{P}{D} = constant = K.$ [$D =$ Density]
