Crucibles are weighed to a constant mass in an oven to ensure that all moisture and other volatile components have been completely removed. This process is important for accurately determining the mass of the material being analyzed and for obtaining precise and reliable experimental results.
What else can I help you with?
Does a full oven take less energy to maintain temperature than an empty one?
No. Consant temperature maintenance depands on the heat energy leakage through the wall of the oven, and that is determined by the local temperatures just outside and inside the wall. What is in the middle of the oven away from the wall is immaterial. If the oven is full, it will take longer to cool down to room temperature than will an empty oven, but that is different from a constant temperature situation.
Can you boil water in an oven?
No, you cannot boil water in an oven. Boiling water requires direct heat, which an oven does not provide.

How much does a microwave weigh in grams?
The first microwave as we know was a radio transmitter, a scientist was standing close to it and noticed that the candy bar in his pocket was melting, therefore, the first microwave probably weighed about 800 pounds. The first commercial microwave oven probably weighed about 180 lbs.If you can remember the mid 70s, whenever a microwave oven was used in a store, the cashier would ask if anyone had a pacemaker. Hope this helped.If so, please 'Recommend Contributor'
What is the scientific explanation of why the temperature is higher at the bottom of an oven?
The higher temperature at the bottom of an oven is due to the fact that heat rises. The heating element in the bottom of the oven generates heat, which then rises to the top of the oven. This creates a temperature difference within the oven, with the bottom being hotter than the top.
What tools will I use as a chemist?
Examples: tongs, crucibles, laboratory stand, burettes, pipettes, balance, oven, Erlenmeyer flask etc.
What is another name for a drying oven?
Another name for a drying oven is an: oast
When was the nuwave oven first introduced to the mass market?
This particular kind of oven was first made in the year 1947. This type of oven would come to be known as a microwave oven and would change the way cooked meals were mad and shortening the time for various foods.

How will you determine when the water has been driven from a crystal?
Weight your sample Heat in an oven then weight them out again, when this weigh is constant then its done.
What are the side effects of eating bread that did not rise in the oven?
you will fall asleep because of all the mass in one space
What are the two methods used to determine the moisture content of wood?
The two methods used to determine the moisture content of wood are the oven-drying method, in which a wood sample is weighed before and after drying in an oven, and the moisture meter method, which uses an electronic device to measure the electrical conductivity of the wood to estimate the moisture content.
How do you obtain dry mass of a seedling?
To obtain the dry mass of a seedling, first carefully remove the seedling from the soil or growth medium. Next, gently pat the seedling with a paper towel to remove any excess moisture. Then, place the seedling in an oven set to a low temperature (around 60-70°C) for a few hours until the seedling reaches a constant weight, indicating that all moisture has been removed. Finally, weigh the seedling to determine its dry mass.
Is the energy output of a magetron in a microwave oven constant or variable?
It's constant. The energy delivered depends on how much "on-time" the magnetron has. HIGH = 100% on time, MED might equal 50% (ten seconds on, tens seconds off).
Does metal increase in mass when heated?
E=mc^2 states that energy is mass and mass is energy. Therefore if you add heat energy to a body its mass increases. For example when water is heated in a microwave oven; the oven adds about 1.11x10^-17 of mass for every joule of heat added to the water. This is a tiny amount but a change none the less.
Is there a difference between Ovendry wood and bone-dry wood?
Wood heated in an oven at a constant temperature of 212°F (100oC) or above until its weight stabilizes is considered bone dry or oven dry. That is, it has zero percent moisture content.http://www.clearpower.ie/glossary.html
How does a Flavorwave oven work?
A Flavorwave oven works quite like other ovens except its design allows it to work for professional cooking. It is circular and you can see through it and see the contents within cooking rather clearly.
