热力学第一定律热力学第一定律thermodynamics，firstlawof普遍的能量转化和守恒定律在一切涉及热现象的宏观过程中的具体表现。热力学的基本定律之一。表征热力学系统能量的是内能。通过作功和传热，系统与外界交换能量，使内能有所变化。根据普遍的能量守恒定律，系统由初态Ⅰ经过任意过程到达终态Ⅱ后，内能的增量ΔU应等于在此过程中外界对系统传递的热量Q和系统对外界作功A之差，即UⅡ－UⅠ＝ΔU＝Q－A或Q＝ΔU＋A这就是热力学第一定律的表达式。如果除作功、传热外，还有因物质从外界进入系统而带入的能量Z，则应为ΔU＝Q－A＋Z。当然，上述ΔU、A、Q、Z均可正可负。对于无限小过程，热力学第一定律的微分表达式为dQ＝dU＋dA因U是态函数，dU是全微分；Q、A是过程量，dQ和dA只表示微小量并非全微分，用符号d以示区别。又因ΔU或dU只涉及初、终态，只要求系统初、终态是平衡态，与中间状态是否平衡态无关。热力学第一定律的另一种表述是：第一类永动机是不可能造成的。这是许多人幻想制造的能不断地作功而无需任何燃料和动力的机器，是能够无中生有、源源不断提供能量的机器。显然，第一类永动机违背能量守恒定律。
