What does change when the state of matter changes?
Matter changing state is usually a result of the material changing temperature and/or a change in the surrounded pressure on the material. The change of state is usually associated with a change in its density.
Is changing the state of matter changing its material?
It may change its measurable properties but a simple state change is brought on by an increase or decrease the energy content of the material and does not alter the material from one material to another.
Does melting cause a change in state?
Yes, the material changes from a solid state to a liquid state.
Consider a material in a solid form that is heated to a very high temperature what phases does the material go through?
When the material reaches its melting point, whatever that may be for the given material, it will go through fusion (will change from solid state to liquid state). Once the material reaches its boiling point it will go through evaporation (will change from liquid state to a gaseous state).
What phase Change?
A phase change occurs when a material goes from a gaseous state to a liquid state, a liquid state to a solid state, or the above in reverse order.
Why did they change the material to make car bumpers?
to make it lighter
What describes any change in matter that does not affect the chemical composition of the material?
Physical change, as change in state.
If you freeze lead is it still toxic?
Yes. A material's toxicity does not usually change after a change of state.
Is mold a chemical change?
No. A material is heated, i.e. changes state, then hardens again. No chemical change, but at least a partial state change.
What do you call the amount of energy needed to change a material from the solid state to the liquid state?
either potential or kinetic
How do chemicals change material?
Chemicals chAnge their state or form when energy is added ie heaT OR COLD CHANGE TO SOLID LIQUID OR GAS
When a physical change in a sample occurs which does not change?
Substance in the material Remain the same
