What defines entropy change,∆S?
A)the sum of heat absorbed and work
B)equal to the heat transferred at constant pressure and volume
C)a measure of disorder in a system
D)pressure change at a constant temperature

Question

Quizplus · Accepted Answer

Entropy change, ΔS, is a measure of the amount of disorder or randomness in a system. It is related to the number of possible arrangements of particles within a system and increases with any process that leads to an increase in randomness or disorder. Options A and B relate more to energy transfer and not specifically to entropy change, while option D refers to a different thermodynamic property, pressure, and not entropy.
