That definition of heat is almost there, but not complete

回答: 不知wasguru是否认可这个定义？由 james_hussein_bond 于 2011-03-21, 19:15:13:

What is incomplete is that, in addition to work that related to external parameters of a system, there are also kinds of work that is not directly related to external parameters. They are called dissipation work. It is this dissipation work that is the gray area in the definition of heat.

- 你要从能量守恒的角度看。如果定义WORK 是机械功， HEAT 就需要包括非机械功的内容。 (无内容) - 不懂相对论 (0 bytes) 2011-03-21, 20:11:50 (565880)
  - 可逆的非机械功肯定不能算在Heat里面 - wasguru (24 bytes) 2011-03-21, 20:16:56 (565886)
