Which of the following is a representation of Gay-Lussac’s law

Options

(a) P₁V₁ = P₂V₂
(b) P₁T₁ = P₂T₂
(c) V₁T₂ = V₂T₁
(d) P₁T₂ = P₂T₁

Correct Answer:

P₁T₂ = P₂T₁

Explanation:

Gay-Lussac’s law: At constant volume, the pressure of the given mass of the gas is directly proportional to its absolute temperature.
P₁ / T₂ = P₂ / T₁(at constant volume)
⇒ P₁T₂ = P₂T₁.
