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 is transferred in several different ways, either conduction, convection, and radiation. Regardless of the method of transfer, only heat can be transferred.Cold is simply the absence of heat and cannot be transferred by any method. Conduction is the transfer of heat from one molecule to another through a substance.Not all substances conduct heat at the same speed. Metals are considered good conductors since they can speedily transfer heat. Stone is also a moderately good conductor, but wood, paper, air, and cloth are poor heat conductors.old is simply the absence of heat and cannot be transferred by any method.
