Gay lussac calculator
The above formula is Gay-Lussac's Regulation named after the French chemist and physicist Joseph Louis Gay-Lussac (1778 - 1850). The statute states that the pressure of a fixed mass of gas at a constant volume is directly proportional to its absolute temperature.
In other words, when temperature increases, pressure increases.
When pressure decreases, temperature decreases.
Similar to the calculations with Boyle's Law or Charles' Law, every synonyms problem involving Gay-Lussac's Law will always give us 3 of the 4 variables. Of those 3 variables, we have to decide which two "pair up" (or which two were measured at the similar time). To pair these correctly, these get designated as "P1" and "T1" or "P2" and "T2" but never as "P1" and "T2" or "P2" and "T1".
1) The temperature of a gas is 30 degrees Celsius and its pressure is 760 torr. If the temperature originally was 40°C, what was the original pressure?
The two variables that were measured at the same time (and can get "paired up") are 30°C (T₂) and 760 torr (P₂).
Yes, we could own classified these as T₁ and P₁ but either way, they are matched properly.

Changing pressure and temperature in a formula: calculating the Gay-Lussac's law.
You already know a verbal explanation of Gay-Lussac's law: let's see how this translates in maths!
What we learned is that pressure and temperature are directly proportional:
p∝T
Even better: they are related by a constant:
p=k⋅T
💡 Apply our pressure converter and temperature converter to switch between measurement units quickly.
And, if you desire to keep all the state variables on the alike side, write:
k=Tp
We confess it; this equation is not much useful. To abuse the potential of Gay-Lussac's formula for temperature and pressure fully, we demand to consider a process, a transformation of the gas.
🙋 We calculate the value of the constant k in our Gay-Lussac's rule calculator: click on to see it!
Say that we initiate from an initial state defined by:
- T1 — Initial temperature;
- p1 — Initial pressure; and
- V — Volume of the container.
And we reach a final state defined by the obeying set of variables:
- T2 — Final temperature;
- p2 — Final pressure; and
- V — Volume of the container.

This tool will calculate any parameter from the equation defined by Gay-Lussac’s law P₁/T₁=P₂/T₂, which includes the P1 gas pressure, T1 gas temperature, P2 gas pressure and T2 gas temperature.
Avogadro’s law states that the absolute pressure of an ideal gas will vary in direct proportion to the variation in absolute temperature of the gas. For an ideal gas, the pressure of the gas is directly proportional to the temperature of the gas, as extended as the volume and amount of gas remains constant.
Formulas
Gay Lussac’s Law is explained with math in the following ways.
The pressure of an ideal gas is proportional to the temperature of the gas:
P ∝ T
The pressure divided by the temperature of the gas in a given state, equals a
This is a tool that calculates the change in pressure or absolute temperature of a fixed mass of gas, if the volume is constant, using Male lover Lussac's Law.
The tool is multi-directional and, therefore, determines which temperature or pressure needs to be calculated based on which statistics has been entered. The most typical scenario is to go in an initial pressure and temperature and either the final pressure or temperature, and calculate the other one. However, it is also possible to calculate either the initial pressure or temperature from the entered final principles. After one of the pressure or temperature fields has been calculated, further data changes product in the re-calculation of the same field unless that field is itself changed or a different pressure or temperature is cleared.
In more detail, the communication that can be entered and/or calculated is:
- The initial pressure of the gas. This does not need to be in any specific unit but should be the same as the terminal pressure unit, if entered.
- The initial absolute temperature of the gas, in kelvin.
- The final pressure of the gas. This does not need to be in any specific unit but should be the same as the initial pressure unit,
