|
Definition
| Energy can be neither destroyed nor created, but only trasformed. |
|
|
Term
|
Definition
| The mode by which heat flows from a hotter(source or emitting region) to a colder region(sink or receiver region) when there is a physical contact between the two regions> |

|
Definition
1) Boundary Layer
2) Corrosion Layer

|
Term
| What is one way that the 2nd Law of Thermodynamics can be stated? |
|
Definition
| 1) No process is possible where the only result is removal of energy as heat from a low-temperature reservoir and absorbtion of an equal amount of energy as heat by a high-temperature reservoir.(water will not freeze when heat is applied). |
|
|
Term
| What is another way that the 2nd Law of Thermodynamics can be stated? |
|
Definition
| That no process is possible where the sole result is the removal of heat from a single reservoir and the performance of an equivalent amount of work.(cannot expect the heat of friction to reverse itself and perform mechanical work. |
|
|
Term
| What is another way to state the 2nd law of thermodynamics? |
|
Definition
| No engine, actual or ideal, when operating in a cycle, can convert all the heat suplied to it into work.(No thermal dynamic cycle can have a thermal efficiency of 100 percent). |
