Hey guy, I didnt think i would ever have to deal with gas laws after i got out of AP chem, but it has showed up again in physics. Tell me what to do. Suppose the volume of a balloon decreases so that the temperature of the balloon decreases from 280K to 240K and its pressure drops from 1.6x10^4 Pa to 1.7x10^4 Pa. What is the new volume of the gas. My question is what was the initial? How do i work this prob.? Thanks for any help.
