− | Isometric (literally "equal dimensions") can refer to a property or process that is symmetrical in all dimensions (i.e. the gas is expanding radially) or to a [[wikipedia:Isometric process | type of thermodynamic process]] where volume is held constant but temperature is free to vary, the exact opposite of the first step in the real Carnot cycle.

In mathematics, an {{w|isometric mapping}} (between metric spaces) is a map that keeps all the distances intact. If we measure the distance the same way throughout the cycle, then isometric expansion (or for that matter, isometric compression) is not really an expansion (or a compression). | In mathematics, an {{w|isometric mapping}} (between metric spaces) is a map that keeps all the distances intact.
