Answer:
V₂ = 150 mL
Explanation:
Given that,
Initial volume of a gas, [tex]V_1=300\ mL[/tex]
Initial pressure, [tex]P_1=40\ kPa[/tex]
We need to find the volume of gas if the pressure is changed to 80 kPa. Boyle's law states that the relationship between pressure and volume is inverse. Mathematically,
[tex]P_1V_1=P_2V_2[/tex]
[tex]V_2=\dfrac{P_1V_1}{P_2}\\\\V_2=\dfrac{300\times 40}{80}\\\\V_2=150\ mL[/tex]
So, the new volume is 150 mL.
