Internal energy associated to a system is the total amount of energy of a system excluding both the kinetic and potential energies as a whole for any external effects and is only accountable for any change in the energies of the system due to the internal order or states. It can be considered as that energy of the system essential to make it ready for any provided state.
Specific heat:
It is the specific amount of heat that is contained in a unit mass of any substance needed to bring about [tex]1^{\circ} rise in its temperature.
Entropy:
It can be defined as the degree of disorientation of the molecules or the extent of disorder of the system. It is the lack in thermal energy of the system to get converted into work (mechanical).
Temperature:
The measure of the heat intensity of a substance on a given standard scale.
Right Hand Rule: Magnetic fields exert forces on moving charges. This force is one of the most basic known. The direction of the magnetic force on a moving charge is perpendicular to the plane formed by v and B and follows right hand rule–1 (RHR-1) "
Scientific knowledge is built as people come up with hypotheses and theories, repeatedly check them against observations of the natural world and continue to refine those explanations based on new ideas and observations.
