What else can I help you with?
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.
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).
In an change matter chanes in size shape or state without changing identity?
Physical change.
Why are changes difficult to reverse?
because they change the identity of the matter
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
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.
Physical Change?
Changes of the matter that do not change the composition of the substance.
What of the following involves a change in the identity of the matter undergoing change?
A change in the identity of the matter undergoing change involves a chemical change. During a chemical change, the substances involved undergo a transformation that results in new substances with different properties. Examples include reactions such as rusting of iron or combustion of wood, where the original materials are fundamentally altered. In contrast, physical changes do not alter the chemical identity of the substance.
What is a characteristic of of matter that is exhibited without a change in identity?
Physical property
What is the term for a process that does not change the identity of a substance?
Many physical changes will not alter the identity. However, some physical changes, such as heating or cooling will result in phase changes and so the identity will be different. While ice and water are chemically the same, they are not identical forms of the substance.
