Is hot glass cracking when placed into cold water a chemical or physical change?
It is a physical change because the chemical composition of the glass does not change.
Is hot glass cracking when placed in cold water a chemical or physical change?
Physical. The glass expands or contracts depending on temperature, when you put a hot glass into cold water part of the glass cools and contracts while some of it is still in it's hot, expanded state.
Is breaking a glass beaker chemical or physical?
Breaking, grinding, cracking are all examples of a physical change. The nature of the substance has not changed, just the size of the pieces has changed.
Is shattering a glass a chemical or physical change?
Shattered glass is a physical change because the identity of the glass does not change.
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 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 breaking glass chemical or physical?
Breaking glass is a physical change, as it does not change the chemical composition of the material.
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.
Is a cracked glass a physical or chemical change?
A physical change.
Is breaking glass chemical or phycial change?
Physical change because the molecules have not changed to form a new substance.
Is breaking glass a chemical reaction?
No, this is a physical reaction because no matter has exchanged etc. Instead, the lattice structure of the glass has been broken- which is simply physical. (Not even that sophisticated a physical change, as glass has no lattice structure.)
Is melting glass is a physical change?
Yes, melting glass is a physical change. This is because only the physical state of the glass changes from a solid to a liquid, while the chemical composition remains the same.
