#### Answer:

We use the

#### Explanation:

We use the

And so...........

That the volume has almost halved is reasonable in that the temperature has not changed very much, BUT the pressure HAS DOUBLED. Provided we use absolute temperatures, we are free to use non-standard units of litres, (or even pints), with these laws of proportionality.
