What are the different types of heat transfer and how do they differ from each other?

There are three main types of heat transfer: conduction, convection, and radiation.

Conduction is the transfer of heat through direct contact between objects or substances. It occurs when heat energy moves from a warmer object to a cooler one.

Convection is the transfer of heat through the movement of fluids, such as air or water. This type of heat transfer occurs when warmer fluids rise and cooler fluids sink, creating a cycle of heat transfer.

Radiation is the transfer of heat through electromagnetic waves, such as light or infrared radiation. Unlike conduction and convection, radiation does not require a medium to transfer heat and can occur through empty space.

These types of heat transfer differ in how heat energy is transferred and the mechanisms involved in each process.
