What happens to the identity of a substance when it makes a physical change?
there is to types of change to a substance chemical and physical in a physical change the result is a mixture also most times you can change your end result into what you started with e.g.freeze-melt evaporate-condesate
How are physical properties differ from physical changes?
Physical properties describe characteristics of a substance that do not involve a change in its chemical composition, such as color or density. Physical changes, on the other hand, refer to alterations in the substance's physical state, like melting or boiling.
Is burning a candle wick a physical property?
No, burning a candle wick is a chemical change, not a physical property. Physical properties describe characteristics that can be observed without changing the substance's identity, while chemical changes involve the rearrangement of atoms and result in a new substance being formed.
Is freezing point a physical property or physical change?
Freezing point is a physical property. It is the temperature at which a substance changes from a liquid to a solid state under standard atmospheric pressure. Physical changes involve a change in state without altering the chemical composition of a substance.
When a physical changes occurs new substance are formed?
False. In a physical change, the substance remains the same even though there may be a change in appearance or state. The molecules of the substance do not rearrange themselves to form a new substance.
What is the diffeference between a physical and a chemical change?
A physical change is when a substance changes, but still keeps its identity. When a chemical change occurs, the substance changes its identity.
In a physical change a substance changes its but not its identity.?
Appearance
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.
A physical property of a substance can only be observed if the substance changes into a different substance?
No, a physical property DOES NOT change the identity of a substance. That would be a chemical property which DOES change the identity.
When a substance changes into a different substance a blank change has occurred?
If form changes but identity doesn't change then it is a physical change.
Physical Change?
Changes of the matter that do not change the composition of the substance.

Is sorting rocks by color a chemical change?
Of course not. It is a physical change. A chemical change occurs when the identity of a substance changes.
Is mowing the a lawn physical change?
Mowing the lawn is a physical change. Cutting your hair isn't a chemical change, it's still hair, and it will grow back :) Chemical changes alter the identity of a substance, whereas physical changes do not.
What is the differences between chemical and physical changes?
chemical- changes identity of substance. some signs: bubbles, precipitate forms, color change, difference in temperature physical- does not change identity of substance. can be homogeneous or heterogeneous. meaning appearing to be the same throughout and appearing to have different parts throughout; respectively.
Is it a physical or chemical change when a substance changes form but it remains the same substance?
it would be physical change because physical change is when the substance stays the same
Is a chemical change a physical blend of two or more components?
No. A chemical change is when the chemical identity of substance or set of substances changes to a new substance or set of substances. Physically blending or mixing two components is a physical change.
