Understanding Entropy Changes
Fundamental Concepts of Entropy
Entropy is a measure of the disorder or randomness in a system and is a fundamental concept in thermodynamics.
ΔS = ∫(dQ/T)
ΔS = mC ln(T₂/T₁)
ΔS = Q/T (isothermal)
where:
- ΔS = Entropy change
- Q = Heat transfer
- T = Temperature
- m = Mass
- C = Specific heat capacity
