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.
Heat can be transferred from place to place by conduction [conduction: The transfer of heat energy through a material-without the material itself moving. ] , convection [convection: The transfer of heat energy through a moving liquid or gas.eat can be transferred from place to place by conduction [conduction: The transfer of heat energy through a material-without the material itself moving. ] , convection [convection: The transfer of heat energy through a moving liquid or gas.
