Conjugate means joined together in a pair, and "'''conjugate variables'''" are pairs of [[variable]]s closely related to each other. An important conjugate variable pair in [[thermodynamics]] is [[pressure]] and [[volume]]. Another important conjugate variable pair is [[temperature]] and [[entropy]]. | Conjugate means joined together in a pair, and "'''conjugate variables'''" are pairs of [[variable]]s closely related to each other.
