Thermal conduction is the transfer of internal energy by microscopic collisions of particles and movement of electrons within a body. The colliding particles, which include molecules, atoms, and electrons, transfer disorganized microscopic kinetic and potential energy when joined, known as internal energy. Conduction takes place in most phases: solid,…
Heat transfer is the transfer of heat or thermal energy between physical systems. So when there is a temperature difference between two bodies, heat is transferred from the hot body to the colder body. There are three common modes of heat transfer – conduction, convection, and radiation. In this article,…
Radiation The color of your home’s exterior influences a lot more than the look of your house. The outside of your house either absorbs or reflects heat, making the inside hotter or cooler. That means the color you select for the outside of your home affects the temperature inside,…
It could simply be that black paint is cheaper… But I believe that the external coils on the back of refrigerators are painted black for the following reason: There is a rule in nature that says “a color that is better at absorbing heat is also better at radiating heat.” …
According to heat definition, it is one of the essential forms of energy for the survival of life on earth. Transfer of heat takes place from one body to another due to difference in temperature as per thermodynamics. We use heat energy for various activities like cooking, ironing, transportation,…
