Make sure to use tongs if dish is hot, as to protect skin from burns

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.

evaporating dish and watch glass
it is a dish that evaporates with chemicals
The evaporating dish would not be harmed if it was heated on a hot plate, but it should be heated on a bunsen burner.
Evaporating dish is usually made out of glass.It is shaped like a saucer.It is used mostly when dealing with inorganic aromatic compounds.
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.
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.
Evaporating dishes are used to boil solutions. Crucibles are used to heat solids very strongly.
