How can bumping be avoided when water is being heated in a beaker?
in order to minimize liquids bumping effect during boiling, the container should be uncovered so that the atoms would have enough space to move. During boiling, the atoms react to heat causing the increase motion.
Can liquids with similar boiling points be separated using fractional distillation?
No, due to the fact that fractional distillation uses the difference in boiling points of liquids to seperate them, therefore in order to perform fractional distillation there should be a difference of at least 1degree centigrade
What are distillation bumping flasks?
When a liquid boils, it will change in volume by a large amount. This 'change of phase' as it is known will expand the bubble away from the flask. According to the laws of reaction, this will give the flask a push in the opposite direction, and the flask could jiggle.However, boiling of liquids, or change of phase in general, takes place at a tiny point only. At a tiny imperfection, not over a region. [Notice how the bubbles in a soda drink appear to come from discrete points on the container?]Into a bumping flask we introduce some inert material (perhaps glass beads - perhaps plastic chips?) so this introduces imperfections into the process, and enables the boiling to take place more easily. And that means in a less energetic fashion. The bubbles should be smaller.I trust this is the bumping flask to which you refer.
Boileezer shouldn't put in hot liquid?
Boiling chips (one of the more common brands is Boileezer) should not be placed in a hot liquid since they may very rapidly start the liquid boiling. Boiling chips provide nucleation sites for gas bubbles to form in a hot liquid. They prevent the liquid from absorbing excess heat and spontaneously boiling all at once (called bumping). If you place a boiling chip in a hot liquid that is at its boiling point, it will spontaneously boil and could splash out of the heating vessel.
What is the boiling point of Vicodin?
Because Vicodin is a solid, it is not relevant to ask it's boiling point - only liquids boil.Rather, with solids one measures a "melting" point, that is, the temperature at which a solid melts to a liquid, before it 'burns' or oxidizes.Standard references, such as a PDA or encyclopedia should have the melting point, if you enter the correct chemical formula.
Why should bumping granules used when boiling liquids?
To avoid splashing of liquids.

The boiling point of both the liquids should be known during separation by fractional distillation method.why?
Separation by distillation is based on the differences between boiling points.
In heating liquids in a test tube why is the test tube move back and forth across the flame?
You should only heat liquids in the wider kind of test tube known as a boiling tube. Using an ordinary test tube often results in rapid local boiling and consequent shooting out of the liquid, which is known as 'bumping'. That said, many people prefer to move the tube around in the flame at first to prevent uneven heating of the contents, and to produce smoother boiling. There is a very small chance that concentrated heating may put stress on a weak spot in the glass and cause it to break.

Why should the total amount of liquids introduced into a test tube not exceed half the capacity?
Because when boiling some water may come out of the test
Distillation can be used to separate solutions of miscible liquids because ?
Distillation works because liquids boil at different temperatures. Roughly speaking, in order to separate two liquids, you should heat the mixture to a temperature where one of the liquids (but not the other) is past its boiling temperature. Then the first liquid will boil off, leaving the second liquid behind; you can collect the first liquid in a condenser.
What do you feed a goldfish if you can't get the flakes?
you should feed it Granules that they sell in pet stores just ask somebody and they will give you the one that you are going to need here is the name of one of the Granules you can give a gold fish: Aqueon Goldfish Granules. i hope that answers your question

When should boiling point be recorded?
When the liquid is boiling steadily and the temperature has stabilised.
