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.
Boiling point. Boil the water, the water will turn into steam leaving only the glass.
Its solidity, would prevent it from passing through a filter, whilst the water would pass through.
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.
Blowing glass is a physical phenomenon, or 'property'.
Physical
yes it is is a physical property
Broken Glass
It is a physical change.
No, it is a physical change as the identity of the substance remains the same. Broken glass is still glass.
Purely physical.
Yes,because a force had to act on it
Add water to the mixture, sugar will dissolve, glass will not. Filter the liquid (the broken glass will be the residue) and evaporate to filtrate to get sugar.
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.)
If it is resting on the floor, there is no change at all.
not sure! but i know they do share hardness !
