Temperature only effects mass by a very little amount. A high school lab including chemical reactions and using a scale that measures to the hundredth or thousandths place won't be effected by temperature. One reason that you must wait for the dish to cool could be for safety precautions, or possibly just to prevent damage to the scale. It all depends on the situation.

∙ 9y agoAn evaporating dish must cool before measuring the mass of a substance. This is so that the energized particles settle and the mass can be measured accurately.

∙ 12y agowell you must wait for an evaporating dish to cool before measuring its mass because all the water has in the dish has to evaporate.... I think this is the answer I'm just guessing:) hahahaha

∙ 13y agoMore Vapours come out of evaporating dishes when hot, and there is loss of some weight during this process. So the mass is measured after cooling.

What is mass of evaporating dish?
it is a dish that evaporates with chemicals
Can an evaporating dish be heated on a hot plate?
The evaporating dish would not be harmed if it was heated on a hot plate, but it should be heated on a bunsen burner.
What is an evaporating dish and how is it labeled?
Evaporating dish is usually made out of glass.It is shaped like a saucer.It is used mostly when dealing with inorganic aromatic compounds.
Why use an evaporating dish instead of a beaker for sublimation?
Evaporating dishes are used to boil solutions. Crucibles are used to heat solids very strongly.
A sample of copper powder is heated in an evaporating dish using a Bunsen burner If the mass of the powder in the evaporating dish increases after heating this indicates that?
the copper must have combined with another substance.

What does an evaporating dish looks like?
An evaporating dish is a shallow, wide dish that is meant to create a large surface area exposed to air. It is used to allow liquids to evaporate into the air quickly.
What is an evaporated dish?
An evaporating dish comes in a number of sizes, and are usually made of ceramic or glass. All evaporating dishes are bowl-shaped, though some are a lot shallower than others. the evaporating dish is used for just what you would imagine: evaporating liquids over a heat source. I have also seen the larger (white ceramic) dishes used in titrations, where the endpoint is observed against the white of the dish.

How do you write clean and dry your evaporating dish and place it on the wire gauze resting on the iron ring in the past tense?
I cleaned and dried my evaporating dish and placed it on the wire gauze on the iron ring.
Why is it necessary to handle the evaporating dish only with The Crucible tongs after the initial heating?
It is necessary to handle the evaporating dish only with the crucible tongs after the initial heating because you will burn your hands/feet/whatever appendage you use to pick the dish up with.
