The **Gay-Lussac's Law** calculator computes the initial and final pressure and temperature of an ideal gas based on Gay-Lussac's formula (T_{1}•P_{2}=T_{2}•P_{1}). The calculator automatically handles numerous temperature and pressure units. All of these calculations presume the volume and mass of the ideal gas remains static throughout. Gay-Lussac formula is:

T_{1}•P_{2}=T_{2}•P_{1}

where:

- (
**T**) is the initial temperature using Gay-Lussac._{1} - (
**P**) is the final pressure using Gay-Lussac._{2} - (
**T**) is the final temperature using Gay-Lussac._{2} - (
**P**) is the initial pressure using Gay-Lussac._{1}

This calculator accesses the following equations from its four buttons:

Gay-Lussac Law (final temperature) - equation computing final temperature of an ideal gas given knowledge of the initial temperature/pressure state of the gas before a pressure change

Gay-Lussac Law (initial temperature) - equation computing initial temperature of an ideal gas given knowledge of the final temperature/pressure state of the gas after a pressure change

Gay-Lussac Law (final pressure) - equation computing resultant pressure of an ideal gas given knowledge of the initial temperature/pressure state of the gas before a temperature change

Gay-Lussac Law (initial pressure) - equation computing initial pressure of an ideal gas given knowledge of the final temperature/pressure state of the gas after a temperature change
