text: heat--math--phycis! ouch...? 20 cubic inches of a gas with an absolute pressure of 5 psi is compressed until its pressure reaches 10 psi. what is the new volume of gas? (assume that theres no change in temperature)  --no idea how to figure this out. my book, google, ask doesn't help so im laying it on to you guys and girls. help asap! :d 10 cubic inches. f=σa it's proportional - if there's no change in temperature. so twice the pressure ≡ half the volume.  scalar nature of pressure, in the link below...
