Every time a process occurs, it is usually accompanied by an energy shift. Energy comes in many forms, such as heat, light, and work.
The generation or absorption of energy in various processes dictates that each substance must be associated with a certain amount of energy. Its actual value depends on the nature of the material and the conditions of temperature, pressure, volume and composition.
The sum of various types of energy associated with atoms and molecules, such as electronic energy (Ee), nuclear energy (En), chemical bond energy (Ec), potential energy (Ep), and kinetic energy (Ek). Sum of translational energy (Et), vibrational state energy (Ev), and rotational energy (Er).
Represented by the symbol U or E.
U or E = Ee + En + Ec + Ep + Ek
The energy stored in matter in this way is called internal energy.
U=65-38=27J
