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.
Is the most heat lost by the means of conduction, convection or radiation? Asked by: Shazia Answer The three methods of heat transfer can occur in different ratios depending on the materials and environment. Radiation, for example, is the only method by which internal energy can be transferred through a vacuum.
