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 energy can be transferred by three ways: convection, conduction, and radiation. Conductors, such as metals, are objects that allow thermal energy to move easily through them. Insulators, such as plastic, are objects that do not allow thermal energy to easily move through them.hermal Energy Facts. Thermal energy is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated. Stoves and matches are examples of objects that conduct thermal energy.
