A sample of nitrogen gas at a pressure of 3 atm inside a rigid, metal container at 20.0 °C is placed inside an oven whose temperature is 50.0 °C. What is the pressure of the nitrogen after its temperature is increased? Answer atm
Gay-Lussac's Law states
So let's take the
Then cross multiply, imagine the denominator of
Rigid means the volume doesn't change. As long as it is sealed, the moles don't change, either.
R and R are the same, so they cancel. V1 and V2 are the same (rigid container), so they cancel. You are left with
Change 20C to 293K (T1) and 50C to 323K (T2) and solve for P2
