推荐一些物理化学的资料，并祝物理化学吧越来越好

0th Law ⇒ Defines Temperature (T)
1st Law ⇒ Defines Energy (U)
2nd Law ⇒ Defines Entropy (S)
3rd Law ⇒ Gives Numerical Value to Entropy
▲ First Law
showed the equivalence of work and heat ΔU = q + w, ∫dU = 0 for cyclic process ⇒ q = −w
Suggests engine can run in a cycle and convert heat into useful work.
▲ Second Law
• Puts restrictions on useful conversion of q to w
• Follows from observation of a directionality to natural or spontaneous processes • Provides a set of principles for
- determining the direction of spontaneous change
- determining equilibrium state of system

Kelvin: It is impossible for any system to operate in a cycle that takes heat from a hot reservoir and converts it to work in the surroundings without at the same time transferring some heat to a colder reservoir.

Clausius: It is impossible for any system to operate in a cycle that takes heat from a cold reservoir and transfers it to a hot reservoir without at the same time converting some work into heat.

Alternative Clausius statement: All spontaneous processes are irreversible. (e.g. heat flows from hot to cold spontaneously and irreversibly)

辛苦辛苦~

嗯，这个吧里真的很好，我很受益，等忙完了，我一定好好为本吧服务

楼主好人

很喜欢物理化学吧，但自己的物理化学还在初中水平，感觉在吧里只能乱逛，偶尔遇见吧友提出的几个问题，却是从未听说过的概念，我在吧里可以干什么？

初中有物理化学么

物理化学=理论化学≠物理+化学

我现在明白了，乖乖，原来是概念搞错了，是不是特丢人，看来这个贴吧不适合我，到水平之后再来吧。等我啊

其实就是些热化学 电化学 介质啊 反应机理 不过理论很多 比较飘渺 谁都会又都不会 没学挺好的

其实就是用物理的理论和实验方法来研究化学
