Chapter no 2 : Energy,Energy transfer and General Energy Analysis.
If we take the entire room—including the air and the refrigerator (or fan)—as the SYSTEM, which is an
Adiabatic Closed System since the room is well-sealed and well-insulated, the only energy interaction
involved is the Electrical Energy crossing the system boundary and entering the room
- As a result of the conversion of Electric Energy consumed by the device to Heat the room temperature will rise
- Form of Energy
- Some Physical Insight to Internal Energy
- Mechanical Energy
- Energy Transfer by Heat
- Energy Transfer by Work
- Heat vs Work
- The first law of themodynamics
- The First Law of Thermodynamics for a Control Mass Undergoing a Cycle
- The First Law of Thermodynamics for a Change In State of a Control Mass
In the slides a very detail description about these topics are given for learning these topics you shoult consult with the following slides and for further detail about the thermodynamics you should read the other lecture uploaded on this blog.
