Question

If `3/5 L` of a gas at room temperature exerts a pressure of `15 kPa` on its container, what pressure will the gas exert if the container's volume changes to `1/2 L`?

Answer 1

`P_2=18 " "k Pa`

Explanation:

`P_1*V_1=P_2*V_2`
`3/cancel(5)*cancel(15)=P_2*1/2`
`3*3=P_2*1/2`
`P_2=18 " "k Pa`
