CONDUCTION

homebegin

Conduction is the transfer of heat from warmer to cooler areasbacknextBurner

6

As one molecule is heated it begins to move and shake rapidly. Through this process, all the molecules of an object pass heat from one to another, until they are all hot.

CONVECTIONhomebegin

Convection is the process by which large masses of a liquid or gas move which is carrying thermal energy and also continuously until the system reaches thermal balancebacknext

Circulation

When you heat liquid or gases, atom or molecules which gain energy move upward and cooler ones sink to bottom

return

Move

RADIATIONhomebegin

Radiation does not need medium or particles to transfer heat. backatmospheric
