Chemistry - Thermodynamics - I Question with Solution | TestHub

Internal energy is given by : $E=E_{\text{translational }}+E_{\text{rotaional }}+E_{\text{vibrational }}+E_{\text{bonding }}+E_{\text{electronic }}$ Accurate measurement of some forms of energy which contribute to the absolute value of internal energy for a given substance in a given state is impossible. So difference of the initial state and final state is calculated and is denoted by $$\Delta E=E_f-E_i$$
