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.

What combined wih the magnesium when it was ignited in The Crucible?
oxygen. O2 was combined with magnesium when it ws heated in the crucible
What is a small summary about The Crucible by Arthur Miller?
In the physical device called a "crucible", a small pot is heated, and golden items can be melted. Gold itself melts at a relatively low temperature, while alloying metals and impurities remain solid, and will float to the surface of the liquid gold. This allows the jeweler to skim off the dross, leaving only the pure gold, which when cooled could be fashioned into jewelry. In literature, there are several books and stories that use the crucible as a metaphor for human desires and feelings. By "heating" all of the actors to an emotional feverish pitch, the characters will reveal their flaws and inner demons, allowing the true nature of the person to be revealed.
Why should the crucible be heated to constant mass?
We want to weight exactly only the material - variations of the crucible mass lead to errors. That's why the mass of the crucible must be stabilized.This is very important in gravimetry, it is a basic rule.
Why is it essential for magnesium chloride solution in the crucible to be heated slowly?
If the solution is not heated slowly, the solution could boil over resulting in lost mass and calculation errors
What is a crucible and how are they used?
A crucible is a container that is used to hold things whilst they are heated to very high temperatures and typically melted. In the school chemistry lab they are usually small ceramic pots. A substance is placed in the crucible. A lid may be used to cover it. The crucible is heated, typically with a Bunsen burner. A support system is usually used (such as a triangle of pipe clay on wire placed on a tripod) to minimize the risk of burns. In the wider world crucibles can be huge such as those used in steel manufacture and can be made of different materials.
What is The Crucible by Arthur Miller use for?
its used for collecting the gases that are let out of a solution when it is extensively heated.
What is the use of crucible?
A crucible is used to contain chemical compounds when heated to extremely high temperatures.
What are the uses of clay triangle?
Clay triangle is used to hold a crucible while the crucible is heated.
Why evaporation is faster from a heated crucible?
because it is faster
What combined wih the magnesium when it was ignited in The Crucible?
oxygen. O2 was combined with magnesium when it ws heated in the crucible
Uses of triangular clay in science lab?
The clay triangle is used to hold a crucible while the crucible is heated.
How do you know when a heated crucible has returned to room temperature?
holding your hand about 1 cm above the crucible to test is still hot..Caleb!
What element combines with Magnesium when heated in a crucible?
oxygen...it forms magnesium oxide
WHY EMPTY CRUCIBLE HEATED BEFORE STARTED EXPERIMENT?
The empty crucible is heated AND WEIGHED, so that you can drive off any moisture and/or other particles that might add to the weight of the empty crucible. You will eventually weigh the crucible again at the end of the experiment to determine the weight (mass) of some compound. Thus, it is important to have a correct "starting mass" of the crucible.
