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.
There are three ways that heat can be transferred from one object to another. Radiation Conduction Convection Radiation â¢ Process when heat is transferred in the form of electromagnetic waves. â¢ All objectâs emit radiation depending on their temperature. â¢ Most objectâs emit in the infrared region of the spectrum.! You feel the heat from a campï¬re.
