Question

If the volume of a cylinder is reduced from 8.0 liters to 4.0 liters, the pressure of the gas in the cylinder will change from 70 kilopascals to
what?

Answer 1

(I'm not sure if there is a law for this) logically if you halve the amount of space you will double the amount of pressure so from 70kilopascals to 140kilopascals.

Answer 2

yes it will double as long as temperature ( and the mass ) remains the same, to 140 kilopascals

Answer 3

140kPa

Answer 4

I actually had guessed that in the end but thanks a mil guys :)
