Question

define gay lussac's law of gaseous volumes

Answer 1

 It states that, for a given mass and constant volume of an ideal gas, the pressure exerted on the sides of its container is directly proportional to its absolute temperature.

As a mathematical equation, Gay-Lussac's law is written as either:

{\displaystyle P\propto T\,}, or{\displaystyle P/T=k} or

K=P divided by T

{\displaystyle P_{1}/T_{1}=P_{2}/T_{2}

Answer 2

Gay Lussac's Law Of Gaseous Volume states that when gases combines to form gaseous product a simple ratio exist between the reactants and products at constant temperature and pressure.
Eg: H2+Cl2->2HCl
1vol+ 1vol ->2vol
The ratio of the reaction is
H2:Cl2:2HCl
1:1:2 is the ratio.
