law of thermodynamics
- 热力学定律：指描述能量转化和传递的三条原则。热力学第一定律（能量守恒定律）规定系统内能的变化等于系统所吸收的热量和对系统所做的功之和。热力学第二定律规定在系统内，热量不能从一个温度较低的物体传递到一个温度较高的物体，而不引起系统内其他物体的净变化；在任何不可逆过程中，熵总是增加的。热力学第三定律（内尔斯特热定理）规定在有限次数的步骤中，不可能将系统的温度降低到绝对零度。

1.
N any of three principles governing the relationships between different forms of energy. The first law of thermodynamics (law of conservation of energy) states that the change in the internal energy of a system is equal to the sum of the heat added to the system and the work done on it. The second law of thermodynamics states that heat cannot be transferred from a colder to a hotter body within a system without net changes occurring in other bodies within that system; in any irreversible process, entropy always increases. The third law of thermodynamics (Nernst heat theorem) states that it is impossible to reduce the temperature of a system to absolute zero in a finite number of steps 热力学定律
