What else can I help you with?
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.
What describes any change in matter that does not affect the chemical composition of the material?
Physical change, as change in state.
Why did they change the material to make car bumpers?
to make it lighter
If you freeze lead is it still toxic?
Yes. A material's toxicity does not usually change after a change of state.
Does a change of state not affect a material's texture?
A change of state can affect a material's texture because it alters the arrangement of molecules within the material. For example, when water freezes into ice, its texture changes from liquid to solid, indicating a change in the arrangement of molecules. Similarly, when a metal material is heated and undergoes melting, its texture changes as well.
Can a physical change form a new material?
No, if a new material forms that would be a chemical change. Physical changes always remain with the same material you began with.
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
What constitutes a material change?
A material change is a significant alteration or modification that affects the overall value or characteristics of something. It is usually defined by its impact on the decision-making process or the significance of the change in relation to the original state.
