In the equation w = − P∆ V, why is there a negative sign?
Interpretation Introduction
Interpretation: The thermodynamic work can be should be explained.
Concept Introduction:
Thermodynamic first law of work:
- During the expansion or compression of gases there will be some work done so for the gases substances the work can be expressed by the pressure and volume change it is given by,
- In equation (1) the work done by the system (contains gas) means the expanding work will done.
- In equation (1) the work done on the system (contains gas) means the compression work will done.
Explanation of Solution
Explanation
To determine: The sign of work.
- The expanding work will done means the work should be negative sign.
- The compression work will done means the work should be positive sign...
