NEET Physics Laws of Thermodynamics Assertion Reason Question
Assertion (A): In an isolated system, the total energy remains constant.
Reason (R): An isolated system allows exchange of energy but not matter with its surroundings.
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.
