A flask is essentially a bottle. * In a labs, glass flasks (Erlenmeyer, Florence) are used for mixing heating and storing solutions. Sometimes they are graduated to show the volume of material that they contain.
* Vacuum flasks are more robist, ususally with a side arm to remove gases * Insulated flasks keep things cold like liquid nitrogen
A volumetric flask is a container that is used to measure the volume of a liquid with extremely high accuracy. It is the best way to measure a specific quantity of a liquid.
It cannot be used to measure just any volume (unlike a graduate cylinder) -- each volumetric flask is designed to measure one specific volume. Because of that they come in a variety of sizes, such as 1 mL, 5 mL, 10 mL, 25 mL, 50 mL, 100 mL, 250 mL, 500 mL, 1000 mL, 2 L, and 5 L.
A volumetric flask is tear-drop shaped, with a very long neck and a round section at the bottom (and a flat bottom so that it stands upright on a flat surface)
In a volumetric flask, you should also fill the flask until the bottom of the meniscus is at the level of the marked ring around the neck of the flask. Hold the flask at eye level and carefully add liquid (drop by drop if necessary) until the bottom of the meniscus is exactly at the level of the marking on the neck of the flask.

A filter flask makes water clearer Eleanor xxx
A filtration flask is a container used to collect the filtrate from the filtering.
If you think to a Florence flask this is used as a container for liquids.
use as container & gas container
MY ANSWER:A glass flask used in a laboratory for holding chemical liquids and solutions, which has a spherical shape for uniform heating, and one or more long cylindrical necks.
it consists a double walled glass vessel having a vaccum between the walls.both these walls are silvered on the vaccum side.no heat can enter or leave the inner flask by convection oor conduction across vaccum.a small amount of heat can be gained by the flask through by radiation but the silver surface to control radiant heat and reduce it to a minimum
It is called callback function. For an example see the qsort function.
A function is not deigned in to another function. It is because that would lead to dependency injection.
yes, we can not declare a function in the body of another function. but if we declare a function in the body of another function then we can call that very function only in that particular function in which it is declared; and that declared function is not known to other functions present in your programme. So if a function is required in almost all functions of your programme so you must declare it outside the main function i.e in the beginning of your programme.
what is the function of florence flask
"Function?" It's a flask. You put stuff in it. There's not a whole lot of functioning involved.
The distilling flask helps in the separation of two liquids.
A conical flask is used to hold chemicals and to make your chemical.

A volumetric flask is used to contain a specific volume of liquid. It is generally used in chemistry.
Uses of the Florence flask: - to contain liquids - to boil liquids - to realize chemical reactions
A round bottom flask is called a boiling flask. I tolerates the stresses of heating better than flat bottom or Erlenmeyer flasks.
to measure liquids and other chemical fluids
It is used to heat liquids or to made chemical reactions.
A florence flask (also known as a boiling flask) is a type of flask. It is a piece of laboratory glassware. It can hold chemical solutions. The flask has a round body with a long neck. The flask usually come in volumes of 1 liter. It is similar in shape and function to a round bottom flask. See the Web Links and Related Questions to the left for more information.
