- I, II and III
- II and III
- I and III
- I and II
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Gay Lussac’s law (pressure law) states:
(P)/(T) = constant (at constant volume)
Step 2: From this:
(P₁)/(T₁) = (P₂)/(T₂)
⟹ P₁T₂ = P₂T₁
Step 3: P₁V₁=P₂V₂ is Boyle’s law, not Gay Lussac’s law.
Hence, statements I and II are correct.
