Question

What is the Gay-Lussac's Law?

Answer 1

An old gas law....

Explanation:

This law was an experimental gas law that found that for a given MASS of gas...

`PpropT`...given conditions of constant volume....

And so given this proportionality, `P=kT`...but given a constant mass, i.e. quantity of gas, this equlity should hold across DIFFERENT pressures and temperatures...

And so solving for `P/T=k`...and as temperature and pressure EVOLVES....the equality is maintained, and so....

`P_1/T_1=P_2/T_2`.....

As the molar quantity of the gas evolved, this law could be expanded to the Ideal Gas Law....`PV=nRT`...
