Broken glass is a physical change because the glass does not undergo any chemical changes by being broken. The glass could be returned to its original shape through physical means (melt and reform it). Glass is mostly silicon oxides, and the chemical bonds between the silicon and oxygen (which comprise the bulk of common glass) are not affected by breaking the glass.
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.
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.
that depends. changing the shape of glass is physical but if its a glass that can be effected by heat then if can be chemical. i would say its both.
Cutting a glass tube is a physical change because the cut glass tube still has the same chemical composition as the uncut tube. Nothing has changed except the physical appearance of the glass tube.
physical changes~ cutting of paper, parked car, melting butter, flat basketball, and broken glass. chemical changes~burning gas, reacting iron with sulfur, vaporizing water.
No breaking glass is not a chemical reaction, which is what i think you mean. Breaking the glass does not alter the chemical makeup or properties of the glass. Instead breaking glass is a physical reaction because it does alter the size of the glass and its appearance
Blowing glass is a physical phenomenon, or 'property'.
Yes, scratching glass is a physical property because it is a change that can be observed without altering the chemical composition of the glass. It is a physical change that affects the appearance and surface structure of the glass.
A physical property of glass is its transparency, allowing light to pass through without scattering.
A physical property, such as hardness, is what allows a material to scratch glass. Materials with a hardness greater than glass (5.5 on the Mohs scale) can scratch it. Chemical properties do not directly influence the scratching of glass.
Broken Glass
It is a physical change.
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.)
No, it is a physical change as the identity of the substance remains the same. Broken glass is still glass.
Purely physical.
To separate a broken bottle from large sugar crystals, you can use a sieve or strainer to strain the mixture. The broken glass pieces will be caught in the sieve while the larger sugar crystals will pass through. Remember to handle the broken glass carefully to avoid injury.
Yes,because a force had to act on it
