Imagine that you have a 5.00 L gas tank and a 4.00 L gas tank. You need to fill one tank with oxygen and the other with acetylene to use in conjunction with your welding torch. If you fill the larger tank with oxygen to a pressure of 105 atm, to what pressure should you fill ...

I just have a quick question for you. Do I use Charles' Law to solve the following problem, if not, how should I approach this? If a 5.0 sample of a gas undergoes an increase in temperature under constant pressure,what is a possible new volume? Thanks for your help.
