Read the Assertion and Reason below and choose the correct option. — States of Matter and Gaseous State Chemistry Question

💡 Solution & Explanation

Statement I is Charles's law ($V/T = \text{constant}$), which is correct. Statement II is the original experimental observation made by Charles and Gay-Lussac, which serves as the fundamental basis for defining the absolute temperature scale and deriving the $V/T = \text{constant}$ relationship. Thus, Statement II correctly explains Statement I. Therefore, correct answer is A.
