lina2011 [118]

Answer:

Stove → Pot = conduction, Pot → Egg = convection.

Explanation:

There are three ways in which heat is being transferred from one medium to the other and the means are; radiation, conduction and convection heat transfer.

Radiation is the process in which heat is being transferred through emission in form of electromagnetism. Conduction heat transfer Is the process in which heat is being transferred through contact that is two bodies touching each other. Convection heat transfer is the kind of heat that happens through gases.

Since the heat from the stove touching the pot is the conduction heat transfer.

After the water has been heated up, the gas from the water makes the convection heat transfer.

Answer:

In chemistry, a symbol is an abbreviation for a chemical element. Symbols for chemical elements normally consist of one or two letters from the Latin alphabet and are written with the first letter capitalised.

Earlier symbols for chemical elements stem from classical Latin and Greek vocabulary. For some elements, this is because the material was known in ancient times, while for others, the name is a more recent invention. For example, Pb is the symbol for lead (plumbum in Latin); Hg is the symbol for mercury (hydrargyrum in Greek); and He is the symbol for helium (a new Latin name) because helium was not known in ancient Roman times. Some symbols come from other sources, like W for tungsten (Wolfram in German) which was not known in Roman times.
