To determine for which of the following processes the change in entropy (ΔS) is negative, we need to analyze each option based on the concept of entropy. Entropy (S) is a measure of the disorder or randomness in a system. A negative change in entropy (ΔS < 0) indicates that the disorder of the system has decreased. ### Step-by-Step Solution: 1. **Understanding Entropy Change (ΔS)**: - ΔS = S_final - S_initial - If the final state has less disorder than the initial state, ΔS will be negative. ...
