Is enternal energy convert in kinetic energy and how

It is assumed that this question is conversion of internal energy to kinetic energy.
 
The internal energy is just a form of energy like the potential energy of an object at some height above the earth,
or the kinetic energy of an object in motion. In the same way that potential energy can be converted to kinetic energy
while conserving the total energy of the system, the internal energy of a thermodynamic system can be converted to
either kinetic or potential energy. Like potential energy, the internal energy can be stored in the system.
 
The explosion of chemicals or fireworks can be taken as example of conversion of internal energy to kinetic energy.
Once the chemical reaction started, energy released which is stored as internal energy before the reaction,
causes the fragments to gain kinetic energy

CBSE 12-science - Physics
The number of moles in an elemental sample is just the ratio of the mass m to atomic mass 4. n= A The number of protons N, in an elemental sample is Z (atomic number) times the number of moles of Avogadro's number NA N=ZnN P A Copper has an atomic mass of 63.5 g/mole and 29 protons per atom. If such an atom were neutral, then it would have as many protons as electrons. If you remove electrons from a neutral state, then you get a net positive charge. Given a 54 gram ball of copper with a net charge of 2.2 µC, what fraction of the copper's electrons have been removed?
