What is dielectric heating?
Dielectric heating is a type of heating used in engineering. Insulated materials are heated and then put over an electric field that changes quickly. It is usually used for making plastics and rubber.
Where can one find some common uses for induction heating?
There are many common uses for induction heating. Some include: use of the furnace, cooking, welding, etc. It needs a specific temperature to endure even heating with the source one is using.
What is one result of the uneven heating of earth?
Weather
What is the separation techniques for sublimation?
The technique is simple: heating of the sample.
What is crucible used for?
A crucible is used for heating, melting or calcination of materials.
How would a synthesis reaction cause the mass of a product to be higher than the metal in a crucible?
Heating a metal in a crucible can cause the metal to react with the surrounding gases. thus, when weighing the metal after heating, the mass increases because of the addition of the gaseous elements
What are crucible and cover used for laboratory?
The crucible is used for heating small quantities to very high temperatures.
What is the purpose of taring the crucible before using the incineration process?
It reduces errors caused by variations in the weight of the crucible itself.Taring is accurately establishing the empty weight of the crucible, which can vary with contaminants, residue, or oxides. By repeatedly heating, cooling, and weighing the crucible, until there is only an acceptable variation between weighings, the actual weight of samples before and after incineration can be more precisely measured.

What items is used to distribute heat from a Bunsen burner when heating the bottom of a crucible?
A crucible is placed in a pipestem triangle placed on an iron ring while being heated. This supports the crucible while allowing the bottom of the crucible to be directly exposed to the flame of the Bunsen burner. There is no item that is used to distribute heat from a Bunsen burner when heating the bottom of a crucible. The bottom of the crucible is intended to be exposed to the direct flame of the Bunsen burner.
What is used as a support when heating a porcelain crucible?
The porcelain crucible is used for calcination or melting.
Why is the position of The Crucible lid critical to the dehydration of the salt during the heating process?
it is critical to set the lid just off the lip of the crucible to allow the evolved water molecules to escape on heating.
How did The Crucible theater get its name?
I'm not certain but I imagine it is a combinations of things... Sheffield has a great history of steel making, including 'crucible steel' that was made by heating and melting iron in a container called a crucible. Also, the theatre can be said to be a 'melting pot' of ideas and so likened to a crucible.

What is a little porcelain bowl used for heating solids called?
crucible
During the cooling of the fired crucible water condensed on The Crucible wall before its mass measurement Will the reported percent water in the hydrated salt be reported too high or too low?
The percent of water is determined by the loss is mass after heating the water vapor condensed on the crucible wall before heating.
