Is breaking of glass physical or chemical change?
It is a physical change. The resulting fragments of glass are still glass and of the same composition.
What degrees does glass melt at?
The temperature at which glass melts is highly dependable upon it's chemical composition but average glass melts between 1400 and 1600 degrees Celsius.
Is a glass breaking chemical or physical?
It is a chemical change. It keeps its same chemical composition and is in a reversible state. You can remelt it and once again, make glass.
How does temperature effect glass?
Temperature affects glass like it does anything else. If the temperature of glass gets high enough, it will melt. There is not a typical melting point for glass, as it depends on the composition.
Which describes electron probe microanalysis to determine the elemental composition of glass?
Electrons excite atoms in a sample, which emit X rays characteristic of the elements within the sample.
What is the composition of pumic?
Predominantly Glass
Is glue a pure substance?
No, glass is a mixture. The exact composition depends on the type of glass.
When glass brakes is it a physical change?
A glass breaking is a physical change because the chemical composition of the glass does not change.
What chemical formula does glass stand for?
Glass is a silicate; many types of glass exist, with very different composition.
Is breaking of glass physical or chemical change?
It is a physical change. The resulting fragments of glass are still glass and of the same composition.
Is volcanic glass a mineral?
Volcanic glass is not a mineral. It's composition is complex, and their is no crystalline structure.
What are the composition of magnifying glasses?
Just glass (silicon dioxide)
What is a composition of fluxes and silica fused to make glass?
Frit
Will fake diamond cut glass?
Your answer depends on the composition of the 'fake diamond' and the composition of glass. Each mineral has a rating on the Mohs Scale of hardness. The harder mineral will scratch the softer mineral.
How can breaking a glass jar be a physical change?
Breaking a glass jar changes the physical form of the glass without changing its chemical composition.
How is volcanic glass different from a mineral?
Volcanic glass does not technically contain mineral crystals. The definition of a mineral requires a crystalline structure. Secondly, the chemical composition of volcanic glass could vary widely. Minerals have definite parameters for chemical composition.
Which gets cold faster plastic or glass?
It depends on the composition of each of them.
