Key Learnings: Entropy
Entropy is a metric for a system's unpredictability or disorder.
The mass of a system affects the value of entropy. It has units of joules per kelvin and is represented by the letter S.
The value of entropy can be either positive or negative. The entropy of a system can only go down if the entropy of another system goes up, according to the second law of thermodynamics.
