Definition
- Noun:
- The quality of lacking any predictable order or plan: The state or characteristic of being random, having no definite aim, pattern, or method.
- (In thermodynamics) A thermodynamic quantity representing the amount of energy in a system that is no longer available for doing mechanical work: A scientific measure of disorder or unpredictability within a closed system, often associated with the concept of entropy.
Usage Examples
- Noun (General Quality):
