Write the formula for Gay-Lussac's Law and state what parameters must be kept constant.

Gay-Lussac's law k = (P/T)

Explanation:

It is defined as the pressure of a given mass of gas varies directly with the absolute temperature of the gas, where the volume is kept as constant.

This law otherwise called "pressure Law or Dalton's Law".

Mathematical Notation is given as

K = (P/T)

Where,

P - the pressure of a gas

T - Temperature of the gas (in Kelvins)

K - constant

Gay-Lussac's Law is often referred to as pressure-Temperature Law, where if the gas temperature increases, then so do the pressure and volume of the gas is kept constant.

Mathematical Notation is given as

P∝T,

OR

(P/T) = K
