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.…

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…

This lecture introduce on Earth’s Weather: Oceans and Air Temperature. Here briefly focus on how do oceans affect temperature on land. The ocean plays a fundamental role…

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…

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…

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…

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…

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: ℃)…

Prime objective of this lecture is to present on Vertical Structure of the Atmosphere. It is a tutorial study based lecture. The changes in the atmosphere with…

Basic objective of this lecture is to present on Dalton’s Law of Partial Pressures. Dalton found that the total pressure of mixed gases is equal to the…

General objective of this lecture is to present on Digital Barometer. It is a tutorial study based lecture. A digital barometer measures air pressure. It is used…

Air Pressure is the force exerted on you by the weight of tiny particles of air (air molecules). Although air molecules are invisible, they still…
