What is Heat?
Heat is a form of energy. It derives its origins at the molecular scale. Molecules of a substance vibrate at their positions either fixed or not when energy is supplied to them. As they vibrate they transfer their energy to the surrounding molecules causing them to vibrate as well.
Conduction is the transfer of thermal energy through direct contact. Convection is the transfer of thermal energy through the movement of a liquid or gas. Radiation is the transfer of thermal energy through thermal emission
Examples of Convection
Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. ...
Radiator - Puts warm air out at the top and draws in cooler air at the bottom.
Steaming cup of hot tea - The steam is showing heat being transfered into the air.
Ice melting - Heat moves to the ice from the air.
What is the main difference between conduction and convection?
Difference Between Conduction, Convection and Radiation. While conduction is the transfer of heat energy by direct contact, convection is the movement of heat by actual motion of matter; radiation is the transfer of energy with the help of electromagnetic waves
Which is faster conduction or convection?
Whereas conduction is a static process, convection is a more efficient method of heat transfer because it adds the element of motion. A convection oven heats food faster than an ordinary one because it has a fan that blows the hot air around.
Radiation
Radiation is the fastest mode of transfer of heat, because radiation travels at the speed of light, which is very quick. The slowest mode of transfer of heat is conduction because it takes place from particle to particle.
What is the difference between conduction and convection?
In conduction, heat transfer takes place between objects by direct contact. In convection, the heat transfer takes within the fluid. The heat transfer occurs through a heated solid object.
Conduction
Conduction is the method of transfer of heat within a body or from one body to the other due to the transfer of heat by molecules vibrating at their mean positions. The bodies through which the heat transfer must be in contact with each other. There is no actual movement of matter while transferring heat from one location to the other.

Thanks sir for the understanding topic

[@shadowofsid4160]

Excellent sir
You teach us one topic two timea😌😌😌😊

[@sauravkushwah1612]

Very amazing 🤩🤩🤩

[@dhananjaysingh991]

Sir very well explained, if you can make a video on through induction hardening, it would be of very help.
