A sample of an ideal gas in a closed container (3.00 L) at 25.0 degrees C is heated to 300 degrees C. What is the pressure of the gas at this temperature?
Do I use P1/T1=P2/T2? I was told to use that, but I don't know what pressure is.
Sorry, I posted this earlier, but my question wasn't answered. I don't understand what P1 is to solve this. What am I supposed to do?

DrBob222,
Since P1 can be anything, I don't see how the problem can be solved without that information or without other information that would allow us to calculate P1. If another tutor disagrees, he/she will show you how to do it.
