1. A gas has a volume of 45 L at a pressure of 140 kPa. What is the volume when

pishuonlain [190]

Answer:

The new volume of the gas is 21 L.

Explanation:

Volume of a gas is inversely proportional to its pressure at constant temperature such that,

$V\propto \dfrac{1}{P}$

$P_1V_1=P_2V_2$

We have,

$V_1=45\ L\\\\P_1=140\ kPa \\\\P_2=300\ kPa$

It is required to find V₂. Using above law or Boyle's law such that :

$V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{140\times 45}{300}\\\\V_2=21\ L$

So, the new volume of the gas is 21 L.
