How do you explain convection to a child?

Kids Definition of convection : motion in a gas (as air) or a liquid in which the warmer portions rise and the colder portions sink Heat can be transferred by convection.

What is convective radiation?

Radiation. In conduction, heat transfer takes place between objects by direct contact. In convection, the heat transfer takes within the fluid. In radiation, heat transfer occurs through electromagnetic waves without involving particles.

What is convection radiation and convection?

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. The matter is present around us, in three states, solid, liquid and gas.

What is conduction convection and radiation simple definition?

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.

What is radiation in Kid definition?

Radiation is energy that moves from one place to another. Light, sound, heat, and X-rays are examples of radiation.

How is heat transferred through convection?

Convection. Convective heat transfer is the transfer of heat between two bodies by currents of moving gas or fluid. In free convection, air or water moves away from the heated body as the warm air or water rises and is replaced by a cooler parcel of air or water.

What exactly is the difference between radiation convection and conductivity?

Conduction explains the process in which the transfer of heat takes place between objects by direct contact. Convection refers to the form of heat transfer in which energy transition occurs within the fluid. Radiation helps in the mechanism by which heat is transmitted without any physical contact between objects.

What are the differences between convection and radiation?

Convection heat transfer is the process in which heat transfer in fluids due to the actual movement of molecules. Radiation is the process of heat transfer in which heat transfer without any medium or directly.

What is the definition of radiation heat transfer?

Definition: Radiation heat transfer is the process by which the thermal energy is exchanged between two surfaces obeying the laws of electromagnetics.
