Volcanic Ozone Hole Prime purpose of this lecture is to present on Volcanic Ozone Hole. An “ozone hole” could form over the North Pole after future major volcanic eruptions –…
How is Ozone Formed? Basic purpose of this lecture is to present on how is Ozone Formed. UV radiation strikes the O2 molecule and splits it, atomic oxygen associates itself…
Lecture on Ozone Hole General purpose of this lecture is to present on Ozone Hole. Dramatic loss of ozone in the lower stratosphere over Antarctica was first noticed in the 1970s…
Waves in Electromagnetic Spectrum Properties of waves include speed, frequency and wavelength. All light travels at a speed of 3 s 108 m/s in a vacuum. The electromagnetic spectrum includes,…
Temperature Measurement 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…
