Yes, it will.
The glass was fluid even while cold, though. It is a super-cooled fluid and will flow (imperceptibly slowly) at room temperature.
usally they melt if not it becomes hot when you heat glass you can mold like clay and when you cool it down it becomes a solid
The main cause is that the glass is covering warmer air, heated by the flame, in the beginning. When the flame extinguishes, the air inside the glass starts to cool. Universal Gas Law: PV/T = a constant. Assume P = a constant too (the atmosphere pressure has changed little). Since the air temperature drops, the volume has to shrink too. The water rises up the glass a little to equalize the pressure.
When a solid is heated the particles vibrate more and they break free of the mold they are in. This makes the solid a liquid. if you continue to heat it, the vibrations will get stronger and the particles will start to evaporate. When the particles evaporate, then it would be a gas.
A heat diffuser is used to diminish the concentrated heat of the flame of a burner and thus prevent glass from breaking due to thermal stress.
A new material - glass - is obtained.
because of co 2
Sodium of course...
When glass is heated to a certain point it becomes easy to shape. It can be bent and shaped into many ways.
the bright yellowish orange tells you that there are sodium coumpounds used in making the glass. it is so intense, that it hides the flame color givenoff by Ca+2 & by K+ it needs to be heated to energize the electrons of sodium much like you energize water when you boil it into steam ... i found that on yahoo answers :D -margo

Yes, because if glass is heated it breaks, if glass is not heated it doesn't break.

It is to prevent direct contact of the glass with the flame of the Bunsen burner. This lowers the possibility of the glass shattering when being heated Read more: What_is_the_purpose_of_the_wire_gauze_placed_over_a_bunsen_burner
when glass rod is heated ,it melts. Now a liquid having surface tension ,tends to have least surface area.we know that a spherical surface has least surface area compared to other shapes of same volume.so end of a glass rod becomes round when heated .........geddit :)
Jars are made from glass. Glass is made from sand. When sand is heated over 1000 degrees it becomes a liquid. It is then moulded into a shape while it is hot.
Tempering is the process to add properties to the raw glass and to make it Standard or Toughened. If tempered (Heated) and cooled slowly, it becomes standard glass on the other hand if tempered and cooled rapidly, it gains different properties and becomes tough or is called toughened glass. Check the link below.
A Bunsen burner is not made of pyrex, it's metal. Usually a beaker or flask made out of pyrex glass is heated by the flame from the Bunsen burner.
