Question

Explain the Law of Conservation of Energy.

Answer 1

The law of conservation of energy is one of the basic laws of physics and therefore governs the microscopic motion of individual atoms in a chemical reaction. The law of conservation energy states:

In a closed system, i.e., a system that isolated from its surroundings, the total energy of the system is conserved.

In SI units, energy has units of Joules. 1 Joule = 1 kgms.

Some forms of energy:

1.Kinetic energy - energy of motion.2.Potential energy - energy of ``location'' with respect to some reference point.3.Chemical energy - energy stored in chemical bonds, which can be released in reactions.4.Electrical energy - energy created by separating charges; energy stored in a battery, for example.5.Thermal energy - energy given off as heat, such as friction.
