This is because Hg is an abbreviation of the Latin name of the element, which was hydrargium. With this name the Greeks were referring to the fact that mercury is a silvery liquid at room temperature, rather than a solid like other metals.
We've looked at the three types of heat transfer. Conduction and convection rely on temperature differences; radiation does, too, but with radiation the absolute temperature is important.
By reviewing different examples of heat conduction you can have a better idea of just how heat is transferred within a body due to the collision of neighboring particles. Heat conduction, also known as thermal conduction, is the process where heat is transferred within a body due to the collision of neighboring particles.
