The movement can occur naturally or may be forced through mechanical means. Natural convection occurs in fluids due to the fact that hot fluids will rise through cold fluids since they have a lower density.

WebSep 30, 2016 · September 30, 2016 at 6:15 am. Throughout the universe, it’s natural for energy to flow from one place to another. And unless people interfere, thermal energy — or heat — naturally flows in one direction only: from hot toward cold. Heat moves naturally by any of three means. The processes are known as conduction, convection and radiation.
