Copper transfers the greatest percentage of heat to the contents of the pot (water). As for the shape of the pot ..... lower and about 1" wider on all sides than the heat source.as wide as the heat source.
Distilled water is a nonmetal. It is a type of purified water created through a process called distillation, which involves boiling water and then condensing the steam back into liquid form.
convection
Objects made of materials with high melting points, such as stainless steel, glass, or ceramic, can hold boiling water without melting. It's important to check the specific material's heat resistance before using it with boiling water.
This method brings the food contact surface to a temperature that will kill most harmful micro-organisms, usually 72˚C to 74˚C or over. Heat sanitization can be used in either mechanical or manual warewashing operations.
I was unable to find any information on a "IGEma". If this is a type of a boiling water kettle, you will see the orange indicator light up on the side of the pot when water reaches boiling.
distilled water
The best type of saw for cutting metal efficiently and accurately is a metal-cutting bandsaw.
mmm the best type is aluminum
thermometer
The heat you feel from boiling water is primarily convective heat, which is heat carried by the physical movement of the water molecules. In addition, there may also be some radiant heat from the steam rising off the boiling water.
The type of solution formed when steam from boiling water evaporates into the air is a gaseous solution. As the water vaporizes, it mixes with the air forming a homogenous mixture of water vapor and air molecules.
Metal. That's the best I can do from your question.
