Kinetic energy(动能）—motion of the body or partical Ke=
Potential energy(势能)—position of a particle in a potential gravitation
Internal energy(内能)—related to the internal condition of the body
State functions(状态函数)—a property of a system that has a value that depends only on the current condition of the system, do not depend on how the system get there
Q(热)=quantity of the heat that flows into the system
W(功)=mechanical work done on the system by the pressure applied by the surroundings
W’=all other forms of work down on the system(magnetic磁力 EMF电能)
System+surroundings=whole universe—total energy of the universe can not change
Second law
Entropy(熵)—When summed for both system and surroundings, For any process, the entropy always increase.
Reversible process(可逆反应)—Carried out so slowly that is internal state is never more than infinite similarly removed from equity barium
Carnot cycle(卡诺循环)—ideal gas(ignore molecular inter forces)+reversible process
