=__**Gay-Lussac's Law**__=

Gay-Lussac's law states that as __temperature increases__, the __pressure increases__. (Simply: As ↑ T, ↑ P). In 1802, Joseph Gay-Lussac discovered that the pressure of a fixed mass of gas at constant volume varies directly with the Kelvin temperature.

**__Equation:__**
P 1 /T 1 =P 2 /T 2


 * __Example Problem:

Q:__** //Find the final pressure in atm using Gay Lusscac's Law with the given info:// P 1 =12atm T 1 =4°K P 2 =? T 2 =8°K

__**A:**__ 1) **Write down formula:** P 1 /T 1 =P 2 /T2

2) **Plug in given info:** 12atm/4°K=P 2 /8°K

3) **Simplify:** 3atm/°K=P 2 /8°K

4) **Use Algebra (multiply 8°K on both sides):** (8°K)3atm/°K=P 2 /8°K(8°K)

5) **Simplify and you're done:** P 2 =24atm
