Physics - Thermodynamics - Entropy - Understanding Entropy

A 5-step lesson. Step 1: 'Entropy (S) is a measure of disorder or the number of microscopic arrangements (microstates) a system can have. More possible arrangements = higher entropy.' S = k·ln(W) where W = number of microstates. Step 2: 'Change in entropy for a reversible process: ΔS = Q/T. Adding h
