Why cool the crucible before weighing?
The crucible must be cold before weighing because the heat from the crucible will warms the surrounding air
Why must the crucible be cooled before weighing?
There are a few reasons: Safety, so individual does not get burned; a hot crucible could damage the scale; hot crucible could alter the substance being weighed; a hot crucible as the heat is released into surrounding air, it causes convection air currents when using an electronic scale than measures to multiple decimal places can give a miss reading and give the individual a larger error percentage in their experiment.
Why need to cool The Crucible by Arthur Miller before measuring?
The crucible must be weighted at a constant temperature, generally 20 oC. During an analytical determination - for example - all the weighings must be made at the same temperature. Also a hot crucible has a negative influence on the balance.
Why must covering the crucible with its lid as soon as the magnesium starts burning?
why Covering the crucible with its lid as soon as the magnesium starts burning
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.

How cold in australia must it get before it snows?
It must get below the freezing temperature of water before it snows in Australia. This is because the water in the clouds must be able to freeze.

Do you underline The Crucible?
Yes. When it is a literary work that can stand alone, it must be underlined.
