Is a solid that is crushed a chemical or physical change?
Nope. That is a physical change. a sugar cube that is crushed into powdered sugar is still sugar.
What are the changes do materials undergo in physical change?
In a physical change, materials undergo a change in their physical state or appearance without changing their chemical composition. This can include changes in shape, size, phase (solid, liquid, gas), or state (melting, freezing, evaporating). Physical changes are usually reversible.
What is bulk powder?
A mass of fine loose grains that are made when a solid material has been ground or crushed.
Is solid ice melting to a liquid a physical or chemical change?
Melting solid ice into liquid water is a physical change. It involves a phase change from solid to liquid without altering the chemical composition of water molecules.
When water freezes into solid ice is it a physical change or a chemical change?
This is a physical change. It's still water, just in solid form.
If a solid is crushed to a powder is it a physical or chemical change?
Crushing a solid to a powder is a physical change because the substance's chemical composition remains the same. The particles in the solid are just broken apart into smaller pieces without any chemical reactions taking place.
Is a solid that is crushed a chemical or physical change?

Is powdery a physical or chemical change?
Powdery is an adjective which not require any change!You can have a physical change where a large lump of some substance is ground into powder. Or you can have a chemical change (eg magnesium burning) which leaves a powdery residue.
Is mixing lemonade powder into water a physical change?
Yes, mixing lemonade powder into water is a physical change because no new substances are formed. The lemonade powder dissolves in the water but can still be separated through physical means such as filtration or evaporation to obtain the original substances.
What is bulk powder?
A mass of fine loose grains that are made when a solid material has been ground or crushed.
Is Chalk homogeneous or heterogeneous?
Homogeneous if its a solid chunk or hetero if it's crushed like powder
Is the change from a solid to a liquid a physical change?
Sure, change from solid to liquid is a physical change
Is gold powder still a solid?
Yes, gold powder is still considered a solid substance. It may have a different physical state compared to a solid bar of gold, but gold particles in powder form retain their solid properties.
Is heating hydrated sodium carbonate powder chemical or physical change?
Heating hydrated sodium carbonate powder to remove water molecules is a physical change because it does not change the chemical composition of the substance. The process involves a phase change from solid to liquid (water loss) and does not result in the formation of new substances.
Which chemical convert solid cobalt into powder form?
The transformation in powder is realized by physical procedures.
Setting of a jelly-is it a chemical change?
Yes, it is. This is because there is a physical change. Being a liquid forming a solid. There is a chemical reaction when the hot water is added to the powder, forming a liquid, which is cooled, forming a solid
