if a gas has a volume of 1 L at a pressure of 200 kPa, what volume would it have when the pressure is increased to 400 kPa?! Assume the temperature and number of particles are constant..

Use Boyle's Law:
pV=k,
where p=pressure, V=volume, and k is a constant for that particular system (gas).
200kPa(1L)=k
k=200kPa/L
Now you change the pressure:
400kPa(V)=200kPa/L
V=.5L

I'd say .5L. double pressure should half the volume (like putting weight on cardboard) Of course, I'm probably wrong.

P1V1=P2V2
If you double the pressure the volume will decrease by half.
So, the answer is 0.5 L.
