What is a change in matter where its identity does not change?
A physical change is a change in matter where its identity remains the same. Examples include changes in state (solid to liquid), size (cutting a piece of paper), or shape (bending a metal rod).
What is a property of matter that can be observed and measured without changing the matters identity?
One property of matter that can be observed and measured without changing the matter's identity is its mass. Mass is a measure of the amount of matter in an object and can be determined through various methods like weighing.
Does not change a substances identity physical or chemical change?
A physical change does not alter a substance's chemical composition; it only affects its physical properties like shape, size, or state of matter. Examples include melting, freezing, or boiling.
What is a characteristic of matter that can be observed or measured without changing the identity of the matter?
A characteristic of matter that can be observed or measured without changing its identity is its mass. Mass is a measure of the amount of matter in an object and can be determined through various methods, such as using a balance or scale, without altering the fundamental nature of the substance.
What characteristic of matter that can be observed or measured without changing the identity of the matter?
Physical properties are characteristics of matter that can be observed or measured without changing the identity of the matter. Examples of physical properties include color, texture, density, and boiling point.
A change in matter where its identity does not change?
a physical change
What is A change in the matter that does not change its identity?
A physical change does not change the identity of matter.
Change in matter where its identity does not change?
A change of phase doesn't change the chemical composition of a substance.
In a chemical change the identity of matter does not change?
No, the chemical nature of the reactants is changed.
What is a change in matter where its identity does not change?
A physical change is a change in matter where its identity remains the same. Examples include changes in state (solid to liquid), size (cutting a piece of paper), or shape (bending a metal rod).
A characteristic of matter that is exhibited without a change in identity?
the volume or mass of the matter. it can change states such as solid liquid or gas, which would be deemed to be the same chemical identity, but a different state of matter
Why are changes difficult to reverse?
because they change the identity of the matter
What is a characteristic of of matter that is exhibited without a change in identity?
Physical property
In an change matter chanes in size shape or state without changing identity?
Physical change.
Physical Change?
Changes of the matter that do not change the composition of the substance.
How can you tell if a change in matter is a physical change?
Any change in matter that is does not require the identity of the matter to change is physical. Things like sizzling, popping, effervescence, etc. are physical change. Something to keep in mind though: Anything that burns is undergoing chemical change, no matter what. Any combustion is chemical.
Process that does not change the identity of a substance?
A physical process does not change the chemical identity of a substance. Examples include changing the state of matter (like melting or freezing), dissolving, or distillation.
