What happens when are heated?
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
What is the flame spread rating for glass?
Glass does not burn or contribute to flame spread, so it typically does not have a flame spread rating.
What is molten glass?
Molten glass is glass that is heated to a high temperature until it becomes a liquid. This allows the glass to be shaped or molded into various objects or forms before it cools and hardens back into a solid state. Molten glass is commonly used in glassblowing and glassmaking processes.
If you will take some water in a shallow bowl and insert a candle and insert a glass over the lighted candle soon the flame extinguishes the water level inside the glass will rises up find out why?
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.
What happens when solides are heated?
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.
What type of property is exhibited when when glass tubing is heated over the flame?
because of co 2
Why is yellow color is imparted to the flame when glass is heated?
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
Why is a yellow flame observed when glass rod heated?
The yellow flame observed when heating a glass rod is due to the presence of impurities on the surface of the rod, such as residual organic materials or contaminants. When these impurities are heated, they undergo combustion and emit a yellow-colored flame. Heating the glass rod to a higher temperature can help burn off these impurities and restore a clear flame.
Why can a glassblower bend and shape a piece of glass that has been heated?
When glass is heated to a certain point it becomes easy to shape. It can be bent and shaped into many ways.
What happen if a flask is heated on a flame with a wire gauze?
Heating a flask on a flame with a wire gauze helps distribute the heat evenly and prevents direct contact between the flame and the glass, minimizing the risk of the glass breaking. The wire gauze also helps to spread the heat more uniformly, reducing the chances of hot spots developing in the glass.
What happens when are heated?
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
Does glass looked different when heated opposed to glass not heated?
Yes, because if glass is heated it breaks, if glass is not heated it doesn't break.
How does a glassblower bend and shape glass?
When glass is heated to a certain point it becomes easy to shape. It can be bent and shaped into many ways.
What are jars made from?
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.
What does glass smell like when it is heated?
When glass is heated, it does not have a distinct smell.
What is the difference between tempered glass and glass?
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.
How do you know when to bend the glass tube?
You should bend the glass tube when it is heated evenly to a specific point, usually indicated by a color change from the heat. It is important to bend it slowly and steadily to avoid cracking or uneven shaping of the tube. A glassworking torch or flame is typically used for this purpose.
