Answer:
140 kilopascals should be the pressure of the gas in the cylinder.
Explanation:
Boyles alw:
[tex]P_1V_1=P_2V_2[/tex]
[tex]P_1=70 kilopascals[/tex]
[tex]V_1=8.0 L[/tex]
[tex]P_2=?[/tex]
[tex]V_2=4.0 L[/tex]
[tex]P_2=\frac{P_1\times V_1}{V_2}=\frac{70 kilopascals\times 8.0 L}{4.0 L}=140 kilopascals[/tex]
140 kilopascals should be the pressure of the gas in the cylinder.
