Distinguish, differentiate, compare and explain what is the Difference between Conduction, Convection and Radiation. Comparison and Differences.
What is Conduction ?
Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules
What is Convection ?
Convection is the phenomenon through which heat is transfer due to the movement of particles in the fluids like liquids and gases.
What is Radiation ?
Radiation differs from Conduction and Convection heat t transfer mechanisms, in the sense that it does not require the presence of a material medium to occur. Energy transfer by radiation occurs at the speed of light and suffers no attenuation in vacuum. Radiation can occur between two bodies separated by a medium colder than both bodies.
Difference between Conduction, Convection and Radiation
|1||Conduction is the transfer of heat by direct physical contact.||Convection is the transfer of heat by the motion of a fluid.||Radiation is the transfer of heat by electromagnetic waves.|
|2||It is due to temperature difference. Heat flows from high temperature region to low temperature region.||It is due to difference in density. Heat flows from low density region to high density region.||It occurs from all bodies at temperatures above 0 K.|
|3||It occurs in solids through molecular collisions, without actual flow of matter.||It occurs in fluids by actual flow of matter.||It can take place at large distances and does not heat the intervening medium.|
|4||Conduction is a slow process.||Convection is a slow process.||Radiation propagates at the speed of light.|
|5||Conduction does not obey the laws of reflection and refraction.||Convection does not obey the laws of reflection and refraction.||Radiation obeys the laws of reflection and refraction.|
