Zinc chloride is weighed when it is cold because it is hygroscopic, meaning it readily absorbs moisture from the air. Weighing it while hot could lead to inaccurate measurements due to moisture loss or gain as the salt cools.
It is a scale or balance having a platform on which objects are weighed -it is also called a platform scale.
Yes, a solid can be weighed on a scale. The weight of a solid is the force exerted by gravity on the object, which can be measured in units like grams or kilograms.
A weighing boat is a small, lightweight container used to hold and transfer solid substances during weighing procedures in a laboratory setting. It helps prevent spillage and contamination of the substances being weighed.
A hygroscopic substance absorbs moisture from the air. If an unknown being is being weighed before and after exposure to air, any increase in weight may suggest it is hygroscopic and has absorbed moisture from the air. Additional testing would be needed to confirm this hypothesis.
The duration of Weighed But Found Wanting is 2.13 hours.
"Weighed But Found Wanting" is a phrase that originates from the Bible, specifically from the Book of Daniel in the Old Testament. The phrase refers to a scene where a figure is weighed on scales and found to be lacking in terms of moral or ethical character. It is not a standalone work or creation with a specific date of origin.
No effect, we choose the crucible because it doesn't lose a bit of weight and it doesn't change when we put it on the fire.
yes you idiout
heat rises. less mass i think
Heating an empty crucible before starting an experiment helps to remove any moisture or impurities that may be present in the crucible. This ensures that the crucible is clean and ready for the accurate measurement of the substance being added to it. Heating also helps to prevent any unwanted chemical reactions that may occur between the substance and impurities in the crucible.
A Knight's Tale
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.
The real quote is "you have been weighed, you have been measured, and you have been found wanting. " Wanting means to be found to not measure up; not capable of the certain task at hand. Therefore, to say this would basically mean: you have been tried and you have been tested, and you have been found to not measure up.
Edward Bate has written: 'The speculative and practical atheist weighed in the ballances and found wanting. Two sermons'
"Weighed, measured, and found wanting" is an idiom that originated from the Bible (Daniel 5:27) and means to be evaluated thoroughly and determined to be insufficient, lacking, or unsatisfactory. It is often used to imply someone's shortcomings or failures have been exposed after careful examination.
