In the following questions, a statement of Assertion (A) followed by a statement of Reason (R) is given. Choose the correct option out of the choices given below each question.
Assertion (A): A liquid crystallises into a solid and is accompanied by a decrease in entropy.
Reason (R): In crystals, molecules organise in an ordered manner.
(i) Both A and R are true and R is the correct explanation of A.
(ii) Both A and R are true but R is not the correct explanation of A.
(iii) A is true but R is false.
(iv) A is false but R is true.
(i) Both A and R are true and R is the correct explanation of A
Explanation: when the irregularity occurs in a structure entropy increases, therefore when liquid crystallises into solid entropy decreases because, in crystals, molecule organised systematically.
