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,
[tex]V\propto \dfrac{1}{P}[/tex]
or
[tex]P_1V_1=P_2V_2[/tex]
We have,
[tex]V_1=45\ L\\\\P_1=140\ kPa \\\\P_2=300\ kPa[/tex]
It is required to find V₂. Using above law or Boyle's law such that :
[tex]V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{140\times 45}{300}\\\\V_2=21\ L[/tex]
So, the new volume of the gas is 21 L.
