My mother didn't, actually, but if one's mother did, it was probably to start cooling it right away to reduce the chance that the glass would crack. The spoon draws away the heat and releases it to the air. So while you may need to pour boiling water over a teabag, it does what it needs to to the teabag and then quickly starts to cool.
Mercury Hg -38.8' Now you could consider Hydrogen to be a metal if you are willing to get creative with the definition of metal. In that case it would be −259.16 °C
sodium has a very high boiling point, in fact it's 883 °C
When an acid is placed on a piece of metal, a chemical reaction occurs where the acid reacts with the metal to form a salt and release hydrogen gas. This reaction is known as metal-acid reaction and can result in the metal deteriorating or dissolving depending on the type of metal and acid involved.
Simply: Heat (a flame works nicely) Water (preferably not already boiling) A container (a metal pan will work) A thermometer(grab the meat thermometer, but don't let mom catch you boiling it)
all the elements that has low boiling point than of the water.
Conduction is the process that causes thermal energy to move through the metal spoon placed in a pot of boiling water. In conduction, heat is transferred through direct contact between particles in a material. The metal spoon conducts the heat from the boiling water to its other end, thus heating it up as well.
The metal one - it is the best conductor of heat
It is a tube rack consisting of two waffer cassettes and usually made from metal. The microtubes can be placed between the two cassettes to keep the tube lips tightly closed during incubation in the boiling water.
Metal can boil. Highest metal boiling point is tungsten.The boiling point of Tungsten (W) is 5,828 K, 5,555 °C or 10,031 °F

Boiling point: the temperature when vapours of the material are formed.
Cast iron is a hard and brittle iron that is formed into a particular shape by pouring the liquid metal into a mold.
The boiling point of iron is 2 862 0C.
It depends on the metal. Different metals have different boiling points.
You can buy a metal ball that you place your loose tea into it for dipping into hot water and it acts as a strainer. I guess that is it. To my knowledge it is a round mesh tool in witch the loose tea leaves go in before it is placed in the hot/boiling water for brewing. It is a tea infuser, a kind of strainer.
The heat expands the metal.
Chromium is a metal and metals tend to have high boiling points.
