Applications of Nano Technology in Energy Sector
Energy is a fundamental concept in physics that refers to the capacity or ability to do work. It is a scalar quantity, meaning it has magnitude but no direction. Energy exists in various forms and can be converted from one form to another. The SI unit of energy is the joule (J).
1. Kinetic Energy: The energy possessed by an object due to its motion. The formula for kinetic energy is KE= 1/2 mv2, where m is the mass of the object and v is its velocity.
2.Potential Energy: The energy stored in an object based on its position or configuration. Gravitational potential energy is associated with an object’s height in a gravitational field, while elastic potential energy is associated with the deformation of elastic materials.
3. Chemical Energy: Energy stored in the bonds between atoms and molecules. When chemical reactions occur, this energy can be released or absorbed.
4. Thermal (Heat) Energy: The internal energy of a system associated with the random motion of its particles. It is often transferred between systems as heat.
5. Electrical Energy: The energy associated with the movement of electrons in an electric current. It is a common form of energy used for various purposes.
6. Nuclear Energy: The energy released during nuclear reactions, either fission (splitting of atomic nuclei) or fusion (combining of atomic nuclei).
The law of conservation of energy states that the total energy in a closed system remains constant. Energy may change forms within the system, but the total amount of energy remains constant over time. This principle is a fundamental concept in understanding physical phenomena and is widely applicable in various scientific and engineering disciplines.
