It's not a change at all. It is simply what the firefly does.

But it is a result of a chemical change within the firefly. A chemical reaction involves a transfer of energy. In this case, the energy would go into creating light waves from the molecules in the firefly, causing it to glow.

Is giving off light a physical or chemical change?

I would think it to be a Physical Change. Not chemical.


What is a chemical change?

A chemical change is a change in which a substance turns into a completely different substance that can't be reversed. A chemical change often happens when a substance burns (not to be confused with evaporation or melting of a substance), changes colors, a substance spoils or rusts, photosynthesis or respiration, and/or a substance tarnishes.Some examples are a bike rusting, burning bread to make toast, fireworks exploding, milk spoiling, a leaf changing color, mixing eggs and flour for a batter, baking a cake, etc.A chemical change will NOT dissolve, go through a state of matter (sublimation, decomposition, melting, freezing, evaporation, and condensation), breaking or tearing of a substance, and/or anything that can be reversed back.A chemical change is one in which one or more new substances are formed. Simple examples include burning and rusting.


What are the 5 characteristics of chemical change?

During a chemical change the structure of molecules (as chemical composition) is changed. Signs of chemical reactions may be: - Gas release - Formation of a precipitate - Change of color - Change of odor - Change of pH - Change of aspect - Change of viscosity - Change of the temperature - Visible formation of new compounds


5 examples of science?

Change in temperature, gaseous bubbles, giving off light, change in color, change in properties. These are chemical changes, but it is still five examples of science.


How is a bent paper clip a physical change?

Well, honey, a bent paper clip is a physical change because the shape of the paper clip has been altered without changing its chemical composition. So, technically speaking, bending a paper clip doesn't turn it into a whole new element - it just gives it a new look. It's like giving a makeover to your stationery, darling.

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.


Is grilling a piece of fish chemical or physical?

Grilling a piece of fish involves both chemical and physical changes. The physical change occurs when the fish is heated by the grill, causing it to cook and change texture. The chemical change occurs when the proteins in the fish denature and the Maillard reaction occurs, giving it a different flavor.


When a firecracker explodes giving off light and heat and breaking the wrapper into many pieces is that a physical change chemical change or both?

This is both a physical and chemical change. The explosion involves the release of energy (heat and light), which is a chemical change due to the breaking of chemical bonds. The breaking of the wrapper into many pieces is a physical change as it does not involve any change in the chemical composition of the materials.
