Entropy is a measure of
A.disorder✓ Correct
B.internal energy
C.efficiency
D.useful work done by the system
Explanation
Entropy, in thermodynamics, is defined as the measure of randomness or disorder in the system. It is denoted by S . Higher the randomness or disorder in the system, higher will be the entropy and vice-versa. It is a state function and an extensive property. Entropy order in terms of states of matter is- Gas>Liquid>Solid Thus, the correct option is (a) disorder
