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 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 by Arthur Miller be cooled in a desiccator?
it must be cooled in the desiccator in order to take the correct measurement on the scale while performing the 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.

Why must helium be cooled to 4k before it will condense explain the fundamental process?
The single atoms of helium gas are small, and has small surface area. They must be cooled to 4K before their attractive forces cause them to condense.
Why must the inoculating loop be cooled before touching a culture?
To avoid killing the test subjects before the test can begin.
Why must the inoculating loop be cooled first before touching a culture?
To avoid killing the test subjects before the test can begin.
Why must The Crucible by Arthur Miller lid be left ajar and not tightly covering The Crucible by Arthur Miller?
If not the substances or chemical in the crucible will flow out and drip onto the table
Before ice can form on a lake all the water in the lake must be cooled to?
no it can form any time. ^^^^^^^ thats bS
Why must covering the crucible with its lid as soon as the magnesium starts burning?

Why must the sugar solution be cooled before adding yeast?
It's not clear in what context this question is asked, but hot water can kill yeast.
Why heat must be lost before water turns to ice?
it has to be cooled because ice is cold not warm. it is impossible to make a warm ice cube
