What is Gay Lussac's Law?
Gay Lussac's Law also called the pressure law that states that the pressure exerted by a gas is directly proportional to the absolute temperature of the gas.
It was formulated by the French chemist Joseph Gay-Lussac in the year 1808. This law tells that pressure is proportional to the temperature when there is a constant amount of gas in a closed and rigid container.
Gay Lussac's Law Formula
From the Gay Lussac's Law definition, its formula is P₁/T₁ = P₂/T₂.
Where,
- P₁ is the initial pressure
- T₁ is the initial temperature
- P₂ is the final pressure
- T₂ is the final
The relationship between the pressure and temperature of a gas can be P₁/P₂ = T₁/T₂.
Gay Lussac's Law Derivation
Gay Lussac's Law states that pressure is proportional to the temperature.
P ∝ T
P/T = k
For two different conditions of a gas,
P₁/T₁ = k --- (i)
P₂/T₂ = k --- (ii)
Equating both equations
P₁/T₁ = P₂/T₂
Gay Lussac's Law Example:
Question: The pressure of a gas in a cylinder when it is heated to a temperature of 220K is 1.8 atm. What was the initial temperature of the gas if its initial pressure was 1 atm.
Answer:
Given that,
Initial pressure P₁ = 1 atm
Final pressure P₂ = 1.8 atm
Final temperature T₂ = 220K
Gay Lussac's Law formula is P₁/T₁ = P₂/T₂
T₁ = (P₁T₂)/P₂
= (1 * 220)/1.8
= 220/1.8
= 122.2
Therefore, the final temperature of the gas is 122.22 K.
