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!
When cuso45h2o is heated in a crucible there is a loss of water how is the amount of water loss determined?
Weigh mass before heating and weigh mass after heating. Before mass - after mass.
What element combines with Magnesium when heated in a crucible?
oxygen...it forms magnesium oxide
Why doesnt sucrose have a boiling listed?
Sucrose will decompose (detoriate) when heated up at a temperature before it reaches melting point temperature.
Uses of clay triangle?
The clay triangle is used to hold a crucible while the crucible is heated.

Why is it necessary to cover The Crucible by Arthur Miller when it is being heated?
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.
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.
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

How is it possible that something can have a high temperature but very little thermal energy?
Thermal energy is a product of two variables; the temperature, and the mass. If two objects having the same mass were heated to the same temperature, they would have the same thermal energy. If an object weighing ten grams was heated to 1000º C, it would have less thermal energy than an object weighing 2 tons, heated to 100º C. To demonstrate this, imagine the amounts of ice each of the above objects could melt.
