Maxwell's demon: A gedankenexperiment in which information is used to reduce the entropy of a thermodynamic system; often described as a paradox in relation to the second law of thermodynamics. [e]
This article contains just a definition and optionally other subpages (such as a list of related articles), but no metadata. Create the metadata page if you want to expand this into a full article.
Parent topics
- Thermodynamics [r]: The statistical description of the properties of molecular systems [e]
- Second law of thermodynamics [r]: Entropy S is a state variable of a thermodynamic system; when a system of temperature T absorbs heat DQ reversibly, then dS = DQ/T; during an irreversible (spontaneous) state change dS > DQ/T. [e]
- James Clerk Maxwell [r]: (1831 – 1879) Scottish physicist best known for his formulation of electromagnetic theory and the statistical theory of gases. [e]
