Is production of heat or light a physical or chemical change?
Its a chemical change hottie
Is production of heat or light physical or chemical change?
i think it would be physical because it is still energy.
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.
Is production of light by a lamp physicalnor chemicaln change?
The production of light by a lamp is a physical change. It involves the conversion of electrical energy into light energy through a process that does not alter the chemical composition of the materials involved.
Is Giving off light a physical change?
Giving off light is considered a chemical change, not a physical change. This is because the emission of light usually involves chemical reactions at the atomic or molecular level that result in the production and release of photons.
What does not signal a chemical change color change or production of light and heat or production of gas or change in state?
A change in state does not necessarily indicate a chemical change. Melting, freezing, boiling, or condensing of a substance are physical changes that do not involve a change in the chemical composition of the substance.
Is production of light chemical or physical property?
The production of light can be a physical or chemical property. Physical properties would include phenomena like luminescence or fluorescence, where certain materials are capable of emitting light without undergoing chemical reactions. Chemical properties would include processes like combustion or bioluminescence, where the production of light is a result of chemical reactions taking place.
Is a light bulb on a chemical or physical change?
Physical change
Is switching a light bulb on a physical or chemical change?
Physical change
Is emission of light a chemical or physical change?
Most of the time the emission of light is a physical change but there are some chemical reactions which emit light as a byproduct of the reaction.
Is mixing kool-aid a physical or chemical change?
It is a physical because it showain't chemical ...chemical does one of the three production of heat or light Production of gas or formation of precipitate which is a solid ... anonymous i don't know how ta spell dat a word tho
Changing form without a change in chemical properties?
This would be defined as a physical change. In chemistry, this would be defined as anything from a change in mass or volume to a change in state (solid, liquid, gas). As long as the substance does not change in molecular structure, it is mostly a physical change. Common indicators of a chemical change is change in color, production of light, production of extensive heat, production of uncommon smells, or even bubbling.
