A physical change alters a given material without changing its chemical_____?
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
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.
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.
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.
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.
A physical change is when a substance changes, but still keeps its identity. When a chemical change occurs, the substance changes its identity.
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.
Appearance
No, a physical property DOES NOT change the identity of a substance. That would be a chemical property which DOES change the identity.
If form changes but identity doesn't change then it is a physical change.
Changes of the matter that do not change the composition of the substance.

Of course not. It is a physical change. A chemical change occurs when the identity of a substance changes.
A physical property of a substance refers to characteristics that can be observed or measured without altering its chemical composition, such as color, boiling point, or state of matter. Changes in these properties, like melting ice into water, do not change the identity of the substance itself, as both ice and water are still H2O. In contrast, a chemical change, such as burning wood, transforms the substance into a new identity with different properties. Thus, while physical changes can alter the appearance or state, they do not change the fundamental identity of the substance.
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.
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.
it would be physical change because physical change is when the substance stays the same
