Is it true that production of light is evidence that a physical change may have occurred?
Yes, the production of light can indicate that a physical change has occurred, but it's more commonly associated with chemical changes. In a physical change, light may be emitted due to phenomena like friction or the movement of particles. However, in chemical reactions, light often results from energy release as chemical bonds are formed or broken. Thus, while light production can be a sign of a change, it is not definitive for identifying whether that change is physical or chemical.
What else can I help you with?
Are Fizzing or foaming evidence that a chemical change may have occurred?
yes it s an evidence that a chemical change has been occurred
Is substance melts proof that a chemical change has occurred?
no unless there is a chemical change but there isn't. only a physical change has occurred
What does evidence chemical change mean?
Evidence of a chemical change refers to observable signs that a chemical reaction has occurred. This can include color change, formation of gas or precipitate, temperature change, or production of light. These changes indicate that the substances involved in the reaction have undergone a chemical transformation at the molecular level.
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.
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.

Is the production of light a chemical or physical change?
physical
What is the evidence that learning is taking place in the classroom?
When a change in behaviors has occurred..
What changes gives NO evidence that a chemical reaction has taken place?
Changes such as a change in state (solid to liquid), change in color, change in odor, change in solubility, or change in temperature do not provide direct evidence that a chemical reaction has occurred. These changes can be indicative of a physical change rather than a chemical change. To confirm a chemical reaction, additional evidence such as the formation of new substances, evolution of gas, or consumption of reactants is necessary.
When substances are formed that are different from the starting substances has physical change occurred?
No, a physical change refers to a change in the form or appearance of a substance without any change in its chemical composition. If new substances are formed with different chemical properties, then a chemical change has occurred, not a physical change.
When objects change by tearing crushing or melting but do not change into different substances a?
A physical change has occurred.
When you fix broken chair what physical change occurred?
hahahahhaa
