An important extensive property of all systems in thermodynamics, statistical mechanics, and information theory, quantifying their disorder (randomness), i.e., our lack of information about them. It characterizes the degree to which the energy of the system is *not* available to do useful work.

Home Work Help: Calculating Entropy for Melting Ice - Clarification on answer
The question states: What is the change in entropy for the process to completely melt 8.0 kg of ice at 0°C? … The formulas for Entropy we've been introduced to are:
S = Q/T - for constant temperature
ΔS = ∫dQ/T
For heat:
Q=mcΔT
Q=Lm
ΔQ=CΔT
ΔQ=mcΔT
My approach was find the heat to melt the ice:
Q=Lm
m = 8.0kg …
