Over the years, I have encountered a few Christians who relate entropy to sin, chaos, and death. Is this justified?
I don't think so, at least not scientifically.
Given a system, open, isolated, or close, such as the planet Earth, the universe, or a can of Coke, its entropy measures the system's thermodynamic state in units of J/K. When a system exists, its entropy exists and is theoretically measurable. Joule relates to dynamic energy or work or heat; Kelvin relates to thermal temperature.
The Second Law of Thermodynamics says that the total entropy of an isolated system always increases over time. No external physical force acts upon the system; it is just the nature of atoms and molecules residing inside the system.
Technically, entropy is not a force, and it does not measure the level of chaos either.
How do we understand the ratio J/K? What is this per Kelvin degree?
Given a system at any given time, its absolute entropy H is extremely difficult to calculate accurately. In solving practical problems, scientists often calculate ΔH, the change of entropy of the system over 2 instances of time. ΔH = ∫(dQ/T). It depends on the continuous temperature path. Each infinitesimal heat addition must be divided by the temperature at that point.
How does melting ice increase entropy?
We have 1 g of ice at phase change from solid to liquid. The temperature is fixed. The formula is simplified to ΔH = ΔQ/T where:
ΔH = entropy change
ΔQ = heat of fusion (energy absorbed during melting)
T = temperature at melting point (273K)
For ice melting:
Heat of fusion = 334 J/g
ΔS = 334 J / 273 K = 1.23 J/K Positive ΔS means entropy increases.
There is God who will one day put a stop to the current chaos and sin we observe on planet Earth. Still, the scientific measure of entropy may continue onto the new heaven and new earth. It measures the thermodynamic state of a system, not technically the amount of chaos or sin in the system.
