Question

A gas at a constant pressure of 95 kPa does 110 J of work as it expands from the volume `V` to the volume `2V`. What is the volume `V`?

Answer 1

`1.16 dm^3`

Explanation:

Since `L=P xx Delta V`

and `95 kPa = 95000 N/m^2`

and `110 J = 110 N xx m`

We have `Delta V= L/P= (110N xx m)/(95000N/m^2)=1.16 xx10^-3 m^3 = 1.16 dm^3`.
`1.16 dm^3` is the difference of the new volume and also the initial volume.
