Thermodynamics

Thermodynamics is both a branch of physics and an engineering science that deals with large scale reactions of a system that can be observed and measures and the relationship between properties such as energy, heat, pressure, temperaturework, etc. on a system.  A physicist is generally intrested in understanding the fundamentals of physics like matter and the laws of thermodynamics.  An engineer is generally intrested in the energy system and its surroundings.  Thermodynamics is mostly based on four universal laws found in the laws of thermodynamics.

There are three thermodynamic systems, open, closed and isolated:

  • Open system freely exchanges energy and matter with its surroundings. 
  • Closed system exchanges only energy with its surroundings, not matter.
  • Isolated system keeps the energy and matter within the system and everything else out.  No transfer in or out.
