Isobaric Process
A process taking place at constant pressure is called isobaric process.
1) Work done
2)
A Process Taking Place at Constant Pressure
Isochoric Process
In an isochoric process volume of the system remain uncharged throughout i.e. .
When volume does not change no work is done; and therefore from first law
All the heat given to the system has been used to increase the internal energy of the system.
Isochoric Process
How to Solve the Thermodynamics Problems
Define the system you are dealing with and isolate it from surrounding
Apply the first law of thermodynamics to the processes undergone by the system
Remember the various thermodynamics processes explained earlier.
Make sure to use same units for Heat and work to have in the first law of thermodynamics
Remember the sign of Heat and Work. Heat given is and heat taken is . Similarly, Work done by the system and Work done on the system is
