NEET Physics Laws of Thermodynamics Assertion Reason Question
Assertion (A): Entropy increases when the temperature of a crystalline solid is raised from 0 K to 115 K.
Reason (R): Entropy is a measure of the degree of randomness or disorder in a system.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
Raising the temperature from 0 K increases the motion of particles, thus increasing entropy. Entropy measures this randomness, making R a correct explanation of A.
