a crucible is a small cup-like object used in chemistry because it can resist very high temperatures.
The crucible is used for heating small quantities to very high temperatures.
a crucible and cover
This is a small recpient, thermally resistant used in laboratories for calcining and burning.
The primary function of a crucible is to hold and heat substances at high temperatures, typically used in chemistry labs for melting, mixing, or heating materials. A cover is used to either contain the material within the crucible or to protect it from external contaminants while heating.
a crucible is a metal pot the is used to separate metals. those that are wroth something and those that are not. A crucible is also the name fora witchs cauldron, thus the name of Arthur Millers Text the Crucible.
To drive off any volatile materials that might alter the mass of crucible and cover.
It is necessary to cover the crucible when it is being heated for two basic reasons: primarily, it maintains a higher temperature inside the crucible. Without the lid, the heat simply escapes. Secondly, it keeps the material inside the crucible from splashing out.
There is no alliteration used in the crucible.
A crucible is used for heating, melting or calcination of materials.
Crucible is a laboratory tool which has cover, it can hold on your specimens whenever you perform a experiment. by; frisco baculio jr
A crucible is a container used for heating substances to high temperatures in laboratory settings. A lid is a cover that can be placed on top of the crucible to prevent the escape of substances during heating and to protect the contents from contamination. Together, they are used for controlled heating and chemical reactions in experiments.
I'm assuming you mean a crucible and lid (the little white things you place in ovens or on the top of Bunsen burners)? If you do, then a crucible and a lid is a way to get an anhydrized solid (a solid which may have H2O mixed in amongst the pure solid) and turn it into pure product by evaporating away all of the water in the solid.
