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.

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
