That would be a chemical change because the firefly produces a bio-luminescent chemical. This chemical produces light which you see when the fire fly lights up!
What else can I help you with?
When a firefly emits light is that a physical or chemical change?
Both: The light is produced by organs on the underside of the abdomen and consist of several layers of reflector cells and a lower layer of light-producing cells. These are permeated by nerves and air tubes which supply oxygen to oxidize (with the aid of an enzyme called luciferase) the cell product luciferin.
Is peeling an apple a physical or chemical change?

Is crushing charcoal into powder a physical or chemical change?
Crushing charcoal into powder is a physical change, as it alters the size and shape of the charcoal without changing its chemical composition.
Is Cleaning a painted surface with acid a chemical or physical change?

Is ripping your jeans chemical or physical change?
Physical - there are no chemicals involved
Is a firefly giving off light a chemical or physical change?
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.
If a firefly glows in the dark is that a chemical or physical change?
It's a physical change. A chemical change is when a new substance is formed. A physical change is when something looks, feels, tastes, or smells different, but it's the same substance. You see the firefly is always glowing, it's just the fact that the human eye cannot see it because it is being over powered by the light of the Sun; but it's still the same firefly.
Is Pungent odor a physical or chemical change?
Pungent odor is a physical change because it only affects the sense of smell without altering the chemical composition of the substance emitting the odor.
How could you test whether a chemical or physical reaction occurred?
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 - Change of the state of the matter - A violent reaction with explosion or fire - Bubbling - Emitting a sound - Emitting a light----------------------------------------------------------------During a physical change the molecule composition is not affected.
Is stapling an envelope a physical change or chemical?
A physical change
Is fire in a fireplace a physical or chemical property?
Fire is not a physical or chemical property. Fire is not a property. Fire is a chemical reaction where oxygen combines with some or all of the chemical components of the fuel, emitting light and heat.
