Is melting glass is a physical change?
Yes it is physical change
Is a glassblower creating sculpture out of glass a physical change or a chemical change?
A physical change; you're turning the solid glass into a semi-liquid molten state, forming it into a desired shape, and then allowing it to cool and harden.
Is dropping a penny into a glass of water a physical change?
Yes
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 glass breaking a chemical or physical change and why?
Physical change because before and after breaking a glass, the glass is still SiO2 (Silicon): it's chemical makeup is not changed by the breakage.
Is glass melting a chemical or physical change?
physical change according to physics nd chemical change according to chemistry
Is making molten glass a physical or chemical change?
Melting is a physical process.
Is melting glass is a physical change?
Yes it is physical change
Why is Breaking of glass a physical change?
A physical change can be reversed, for it does not change what the object is made of. The glass, even when broken, is still glass. It can be put back into its original state (possibly through melting) because it never changed what it was made out of.
Is a glassblower creating sculpture out of glass a physical change or a chemical change?
A physical change; you're turning the solid glass into a semi-liquid molten state, forming it into a desired shape, and then allowing it to cool and harden.
Is breaking glass chemical or physical?
Breaking glass is a physical change, as it does not change the chemical composition of the material.
Is dropping a penny into a glass of water a physical change?
Yes
Is shattering a glass a chemical or physical change?
Shattered glass is a physical change because the identity of the glass does not change.
Is glass melting a chemical change?
I believe melting most items is a physical change as you are only changing the state of the matter, not it's composition. There may however be a breakdown that occurs depending on the composition of the glass with high enough temperatures. This would change the chemical composition. I believe you can relate it to melting plastic (don't actually do this as it releases toxic gases). At low enough temperatures it just becomes soft and moldable. At higher temperatures you burn it down and cause changes in the material. I'm no expert
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.
Is a cracked glass a physical or chemical change?
A physical change.
Diamonds are used to scratch glass chemical or physical change?
This is a physical change. There is nothing that changes the components of either the diamond or the glass when the diamond is used to scratch glass.
