Is giving off light a physical or chemical change?
I would think it to be a Physical Change. Not chemical.
Light beam dimmer is chemical or physical change?
A beam of light becoming dimmer is a physical change since it is reversible. Recharging its source will make the light beam bright again.
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.
Mass does not change during a chemical change how about for a physical change?
Physical changes are like cutting paper. The mass does not change. Chemical changes do not change total mass either. If you put a candle in a sealed container so that you may measure the total mass of the candle and the air before burning, then light the candle electrically but keep everything sealed, the total mass after burning will still be the same. But if you measure only the candle, then its mass has changed. So the mass of one single 'ingredient' will change during a chemical change.
Is the production of light a chemical or physical change?
physical
Is production of heat or light a physical or chemical change?
Its a chemical change hottie
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 production of light by a lamp physicalnor chemicaln change?
The production of light is chemical change. I is done by someone.
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.
What does not signal a chemical change color change or production of light and heat or production of gas or change in state?
color change
Is mixing two substances and light is produced a chemical or physical change?
chemical
Is light absorbed in physical change?
Heat absorption is a physical change. It can cause a change in state and/or a temperature increase, but the matter that is absorbing the heat does not change. It retains all of its physical and chemical properties that it had before absorbing the heat.
