STANDARD Physics Entropy MCQ Question
Type: MCQ-conceptual-Easy-Class 11
The total entropy change (ΔSₜₒₜₐₗ) for the system and surrounding of a spontaneous process is given by
A
Sₜₒₜₐₗ = ΔSₛᵧₛₜₑₘ + ΔSₛᵤᵣᵣ > 0
B
Sₜₒₜₐₗ = ΔSₛᵧₛₜₑₘ + ΔSₛᵤᵣᵣ < 0
C
Sₛᵧₛₜₑₘ = ΔSₜₒₜₐₗ + ΔSₛᵤᵣᵣ > 0
D
Sₛᵤᵣᵣ = ΔSₜₒₜₐₗ + ΔSₛᵧₛₜₑₘ < 0
Correct Answer
Option A
Detailed Explanation
For a spontaneous process, total change in entropy (system + surrounding) should be positive.
