First law of thermodynamic
- conservation of energy principle
- during the interaction, energy changes from one form to another and the total energy keeps constant
- energy cannot be neither created nor destroyed, it can only change forms.

Second law of thermodynamic asserts that the energy has quality as well as quantity and the actual processes occur in the direction of decreasing quality of energy.

Zeroth law of thermodynamic
- if 2 bodies are in thermal equilibrium with third body, they're on equilibrium with each other.
- if the third body is replaced by thermometer. Two bodies are in thermal equilibrium if both of them have the same temperature reading even they're not in contact.

System - surrounding - boundary

楼主 Yukino_rou  发布于 2017-10-03 01:55:00 +0800 CST  
System refers to a region in space.
Surrounding refers to the region outside the system.
Boundary is the surface that separate system and surrounding.

Closed system
🌝 a fixed amount of mass
🌝 no mass can across the boundary

Open system
🌝 a property selected region in space
🌝 both mass and energy can across the boundary
