Amwoga Khalwale Microscopic Variable A microscopic variable is a variable pertaining to the individual atoms and molecules, making up the system. Examples include: Component of a particle’s velocity The orientation of the axis of a diatomic molecule The quantum number for a particular vibrational mode of a molecule The magnetic moment vector of a paramagneticion Other examples … Read more
An Otto cycle is an ideal thermodynamic cycle that describes the function of a spark ignition piston engine. The idea of Otto cycle was first proposed by Nicolas Otto back then in 1876. It is the thermodynamic cycle most commonly found in automobile engines. It describes what happens to a mass of gas as it … Read more
An intrinsic semiconductor is one which is made of the semiconductor material in its pure form (Without any significant doping agent present). In this type of semiconductor, the number of charge carriers is therefore determined by the properties of the material itself and not the amount of impurities. It can also be described as one … Read more

The triple point and critical point are both found on a phase diagram. They are terms used to explain temperatures and pressures at which two or more phases of substances can coexist with each other. The critical point is the condition at which the liquid and vapour phase of the same substance coexist. The triple … Read more
A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion chamber of the engine. It gives each intake cycle of the engine more oxygen, allowing it burn more fuel and do more work, thus increasing power. The power for the supercharger can be provided mechanically by … Read more
A turbine is a rotatory mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator. There are two types of turbine Impulse and reaction turbine. A reaction turbine is a turbine with … Read more
Orthogonal cutting also referred to as 2D cutting is a type of metal cutting in which the cutting tool approaches the workpiece with its cutting edge parallel to the uncut surface and at right angles to the direction of cutting. Thus, tool approach angle and cutting edge inclination are zero. In orthogonal cutting, only two … Read more
According to Bohr’s atomic model, an orbit is a fixed circular path along which electrons revolve around the nucleus of the atom. Thus, all atoms particularly revolve in an orbit. According to Bohr model, the first shell holds 2 electrons. However, Bohr’s atomic model has been rejected. The generally accepted model is the one that … Read more
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or many more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam. These boilers include … Read more
