Question

The pressure of gas in a cylinder is 70 kilopascals. If the volume of the cylinder is reduced from 8.0 liters to 4.0 liters, what should be the pressure of the gas in the cylinder?

Answer 1

140 kilopascals should be the pressure of the gas in the cylinder.

Step-by-step explanation:

Boyles alw:

`P_1V_1=P_2V_2`

`P_1=70 kilopascals`

`V_1=8.0 L`

`P_2=?`

`V_2=4.0 L`

`P_2=(P_1* V_1)/(V_2)=(70 kilopascals* 8.0 L)/(4.0 L)=140 kilopascals`

140 kilopascals should be the pressure of the gas in the cylinder.
