The aim of this lecture is to present on Temperature Measurement. Temperature is a physical property of a system that underlies the common notions of hot and…
Lecture on Electromagnetic Spectrum
Electromagnetic waves come in many wavelengths and frequencies. Each one is useful in different ways. The electromagnetic spectrum is the range of all EM frequencies. The…
Electromagnetic Spectrum: Wavelength, frequency and energy
The electromagnetic spectrum is the complete spectrum or continuum of light including radio waves, infrared, visible light, ultraviolet light, X-rays and gamma rays. An electromagnetic wave…
Tutorial: Heat Transfer
Primary objective of this lecture is to present on Heat Transfer. The transfer of heat is normally from a high temperature object to a lower temperature object.…
Ways of Heat Transfer
There are three ways of Heat Transfer: Convection; Conduction and Radiation. Conduction–transfer of heat between atoms as they collide within a substance. Convection is the movement of matter due to…
Presentation on Air Temperature
Temperature a measure of the average speed at which molecules are moving or vibrating. Air temperature is the rate of motion of gas molecules in the atmosphere…
Lecture on Kelvin Scale
Principle objective of this lecture is to present on Kelvin Scale. The kelvin (symbol: K) is a unit increment of temperature and is one of the seven…
Presentation on Rankine Scale
The aim of this lecture is to present on Rankine Scale. Rankine is a thermodynamic (absolute) temperature scale named after the Scottish engineer and physicist William John…
Lecture on Fahrenheit Scale
Major objective of this lecture is to present on Fahrenheit Scale. In this scale, the freezing point of water is 32 degrees Fahrenheit (°F) and the boiling…
Lecture on Celsius Scale
Main objective of this lecture is to present on Celsius Scale. The Celsius temperature scale was previously known as the centigrade scale. The degree Celsius (symbol: ℃)…
