Is giving off light a physical or chemical change?
I would think it to be a Physical Change. Not chemical.
Is production of heat or light physical or chemical change?
i think it would be physical because it is still energy.
What kind of chemical changes produces heat?
Exothermic chemical reactions release energy in the form of heat and sometimes light. A common example would be the combustion (oxidation) of methane*:Methane: CH4 + 2O2 -----> CO2 + 2H2O + Energy (heat and light)* The combustion of methane (natural gas) is commonly used to heat water, cook, and to heat homes.
What Energy Transformations are in a flashlight?
it would be heat to light or chemical to electrical to light
What type of change that produces a new substance?
If you mean changing one element into another, like uranium 238 into plutonium 239, which happens in nuclear reactors, the word is 'transmutation'. Otherwise many chemical reactions form new substances, without the elements involved changing, and these would be called 'chemical reactions'.
What chemical change produces light and heat?
steel wool burns in oxegen and produces heat and light
Give an example of a chemical change that produces light and heat?

What type of chemical change produces heat?
Exothermic reactions. E.g. combustion, oxidation
Ignition of matches a chemical or physical change?
chemical change because there is release of heat, light and energy.
What type of chemical reaction often produces energy in the form of light heat or electricity?
synthesis
Is matchstick an example of chemical energy to light energy?
Yes, although a matchstick produces heat as well as light. Anything that you burn or eat is chemical energy.
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.
Why are vitamins kept in colored bottles to prevent a chemical change of heat or light?
