To determine if a physical change has occurred, observe whether the substance retains its chemical composition. Key indicators include changes in state (such as melting or boiling), shape, or size without altering the substance's identity. No new substances are formed in a physical change, so if the original material can be recovered in its original form, it confirms a physical change. Additionally, physical changes are usually reversible, further distinguishing them from chemical changes.

Is a pellet of sodium is sliced in two a physical change or a chemical change?
Physical, because each slice of pellet is still the same chemically: you have merely divided your one sodium block into two blocks of sodium. If it were chemical, some kind of notable chemical difference would have occurred (you would no longer have sodium, but something else).
How would you determine if a chemical change had occurred?
Some characteristics of a chemical change are: - change of smell - change of color - release of gases - change of temperature - formation of a precipitate - change of the aspect - change of pH in solutions - change of viscosity - flames or explosion etc.
What is a sign that a chemical change has occurred smoke broken pieces change in shape or change in state?
The production of smoke from something burning would be a sign of a chemical change. Broken pieces, change in shape, or change in state are all physical changes.
Would you get a physical or chemical change if you broke a mineral in half?
Physical change
What would suggest that a physical change has take place in an ice cube?
A physical change in an ice cube can be suggested by the melting process, where the solid ice transforms into liquid water as it absorbs heat. This change is reversible, meaning that the water can freeze back into ice if cooled again. Additionally, there would be no alteration in the chemical composition of the water, remaining H2O throughout the process. Observing changes in shape, size, or state without any chemical transformation indicates a physical change has occurred.

How would you determine if a chemical change has occurred?
You can determine if a chemical change has occurred by looking for signs such as a change in color, formation of a precipitate, evolution of gas, or release of heat or light. Additionally, if the chemical composition of the substance has been altered, it is likely that a chemical change has taken place.

Physical change
Would freezing an object be physical change or chemical change?
Physical changes and Chemical changes are both the same - this would be a reversible change.
If you have a bowl of milk and cheerios would it become a chemical or physical change?
physical change
What change in a crushing a can?
Crushing a can would be a physical change. It would only change the shape.
Is Slicing a banana a physical or chemical change?
Purely physical.
Is a chemical change like soild resulting in a change of state of matter?
no, that would be a physical change.no, that is a physical change.
