Heat transfer is the process by which thermal energy is exchanged between two or more objects or systems.
What are the different types of heat transfer?
There are three types of heat transfer: convection, conduction, and radiation.
What is convection?
Convection is the transfer of heat through the movement of fluids or gases. An example is the transfer of heat from a boiling pot of soup to the surrounding air.
What is conduction?
Conduction is the transfer of heat through direct contact. An example is the transfer of heat from a hot stove to a pot sitting on it.
What is radiation?
Radiation is the transfer of heat through electromagnetic waves. An example is the transfer of heat from the sun to the Earth.
What is a heat transfer system?
A heat transfer system is a system designed to transfer thermal energy from one location to another. Examples include air conditioning units and refrigeration systems.
What are some common applications of heat transfer?
Some common applications of heat transfer include cooking, heating and cooling buildings, and industrial processes such as refining metals and plastics.
