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.
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.
No, you cannot boil water in an oven. Boiling water requires direct heat, which an oven does not provide.

No, a microwave oven is not a Faraday cage.
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'
Examples: tongs, crucibles, laboratory stand, burettes, pipettes, balance, oven, Erlenmeyer flask etc.
Another name for a drying oven is an: oast
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.

Weight your sample Heat in an oven then weight them out again, when this weigh is constant then its done.
you will fall asleep because of all the mass in one space
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.
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.
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).
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.
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
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.
