t1 | Initial Temperature(K) | 300 |
t2 | Final Temperature(K) | 450 |
How It Works
Gay-Lussac's Law
At constant volume, the pressure of a gas is directly proportional to its absolute temperature.
Formula
P1 / T1 = P2 / T2
Heating a gas in a rigid container increases its pressure.
Worked Example
A sealed container at 1 atm and 300 K heated to 450 K.
p1 = 1t1 = 300t2 = 450
- 01P1/T1 = P2/T2
- 02P2 = P1 * T2 / T1
- 03P2 = 1 * 450 / 300
- 04P2 = 1.5 atm
