You have a 4.0 L steel tank containing hydrogen gas. You are able to heat or cool the tank, and measure the pressure of the gas.
At what temperature, in Celsius, would you read a pressure of 4.5 atm ?
Wouldn't that depend upon how much H2 is in the tank. I have seen this problem several times in the last 2-3 days. This is only a piece of it. Post the entire problem before I can check this part of it.
