If the pressure on a gas at -73'C is doubled but its volume is held constant, what will be its final temp be?

Gay-Lussac's Law says as pressure goes up, absolute temperature (Kelvin temperature) goes up.





If you double the pressure, you are doubling your temperature as well.





-73°C = 200 K





200 x 2 = 400 K = 127°C

If the pressure on a gas at -73'C is doubled but its volume is held constant, what will be its final temp be?
-146
Reply:-149'c... the volume has nothing to do with anything
