Change in entropy does not depend on:
Correct answer: D. Amount of the substance
- A. Amount of heat added to the system
- B. Amount of heat rejected from the system
- C. The temperature of the substance
- D. Amount of the substance
Explanation
The change in entropy is defined as ΔS = ΔQ/T, where ΔQ is the heat transfer and T is the temperature. While the total entropy of a substance depends on its amount, the change in entropy during a process is determined by heat transfer and temperature, not the initial amount.

About System, Surroundings and State Functions
A system is the part of the universe under study, while everything outside it is the surroundings; the boundary separates them. State functions such as pressure, temperature, volume, internal energy and enthalpy depend only on the state, unlike heat and work, which depend on the path taken.
