焓 Enthalpy

（重定向自Total heat）

焓（enthalpy，读音ㄏㄢˊ|hán）是一个热力学系统中的能量参数。规定由字母H表示（H来自于英语Heat Capacity（热容）一词），单位为焦耳（J）。此外在化学和技术文献中，摩尔焓Hm（单位：千焦/摩尔，kJ/mol）和质量焓（或比焓）h（单位：千焦/千克，kJ/kg）也非常重要，它们分别描述了焓在单位物质的量和单位质量上的定义。

焓是内能和体积的勒让德变换。它是SpN总合的热势能。

T–s diagram of nitrogen.[14] The red curve at the left is the melting curve. The red dome represents the two-phase region with the low-entropy side the saturated liquid and the high-entropy side the saturated gas. The black curves give the T–s relation along isobars. The pressures are indicated in bar. The blue curves are isenthalps (curves of constant enthalpy). The values are indicated in blue in kJ/kg. The specific points a, b, etc., are treated in the main text.
Schematic diagram of a compressor in the steady state. Fluid enters the system (dotted rectangle) at point 1 and leaves it at point 2. The mass flow is ṁ. A power P is applied and a heat flow Q̇ is released to the surroundings at ambient temperature Ta.

Enthalpy /ˈɛnθəlpi/ is a measurement of energy in a thermodynamic system. It includes the internal energy, which is the energy required to create a system, and the amount of energy required to make room for it by displacing its environment and establishing its volume and pressure.
