Why are vacuum flasks called vacuum flasks?
Vacuum flasks are named so because they have a double-wall design with a vacuum-sealed space between the walls. This vacuum insulation helps to minimize heat transfer by conduction or convection, keeping hot liquids hot and cold liquids cold for an extended period of time.
Why are flasks shiny?
Flasks are often made of materials like glass or metal that have smooth surfaces, which can reflect light and create a shiny appearance. Additionally, flasks can be polished or coated with substances that enhance their shine and make them more visually appealing.
Why are volumetric flasks not put into the drying oven?
Because your teacher will probably have a fit. In the old days, you could put volumetric flasks into a drying oven, but you couldn't take volumetric flasks out of a drying oven... the heat would warp the glass slightly and introduce error into the calibration mark, so the flasks would not actually be volumetric anymore. However, borosilicate glass (Pyrex and the like) is much less heat-sensitive, and studies have shown that there's no discernable change in the capacity of borosilicate flasks even after repeated exposure to temperatures considerably higher than those normally found in a drying oven. So, aside from the aforementioned fit, there's no real reason not to do it as long as you're using borosilicate glass flasks.
Why are erlenmeyer flasks specifically used for recrystallization processes?
Erlenmeyer flasks are used for recrystallization processes because their conical shape allows for efficient mixing and evaporation of solvents, which helps in the formation of pure crystals.
Why are flasks shaped the way they are designed?
Flasks are designed with a narrow neck and a wider base to prevent spills and allow for easy pouring. The shape also helps to control the flow of liquids and gases when transferring them.

What does boyle's self flowing flask do?
Nothing. It is an imaginary device that does not work.
What are the uses of a flask?
The round bottoms on these types of flasks allow more uniform heating and/or boiling of liquid. Thus, round-bottom flasks are used in a variety of applications where the contents are heated or boiled. Round-bottom flasks are usually used in distillation by chemists as distilling flasks and receiving flasks for the distillate One-neck round-bottom flasks are used as the distilling flasks in rotary evaporators.This flask shape is also more resistant to fracturing under vacuum, as a sphere more evenly distributes stress across its surface.
What is Perpetual in Japanese?

Where can someone get cheap flasks?
A person can get cheap flasks at the nearby stores such as Wal-Mart, Target, K-Mart, and other stores like Staples. A person can also research where to find flasks and get them.
What is a perpetual will?
Perpetual will is will that is indefinite and never ending. Will that does not end and therefore is perpetual. In a sentence: My will is perpetual, I will never stop trying and always believe in myself.
Why are beakers and flasks not used for heating solids?
the heat may not be distributed uniformly if solids are heated in beakers or flasks
What does oyster perpetual mean?
In the 1920s the founder of Rolex watches was having trouble opening an oyster shell. He had the idea to create the first airtight and watertight watch similar to an oyster shell. The watch was also the first self winding watch or "perpetual". Wrong Jane. "perpetual" is the smooth never-ending movement of the second hand. Has nothing to do with the winding.
