Internal energy:
- It is the energy of the system due to the random motion of the particles along with the potential energies of the molecules.
- Change in internal energy during the thermodynamic process is given as,
⇒ ΔU = mCv(T2-T1) -----(2)
Where ΔU = change in internal energy, m = mass, T1 = initial temperature and T2 = final temperature
- The internal of a system of mass m depends only on temperature, Hence the internal energy of any system can be calculated using absolute temperature only.
