What else can I help you with?
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?
you fart on a candle....
What is an example of a chemical change that produces light and heat?
reaction of na [sodium] with water or air
Is production of heat or light a physical or chemical change?
Its a chemical change hottie
What is the chemical change called in a lit candle?
The chemical change in a lit candle is called combustion. Combustion is a rapid chemical reaction between oxygen in the air and the fuel (in this case, the wax in the candle) that produces heat, light, and carbon dioxide.
What chemical reaction produces a flame?
A combustion reaction is a chemical reaction that produces a flame when a fuel (such as a hydrocarbon) reacts with oxygen (from the air) to produce heat and light. This process releases energy in the form of heat and light, resulting in the flame that we see.
What type of chemical change produces heat?
Exothermic reactions. E.g. combustion, oxidation
Is heat light and change in odor indicate a physical change?
Heat, light, and change in odor can indicate a physical change depending on the context. For example, melting ice into water is a physical change because it does not alter the chemical composition of the substance. However, if a substance undergoes a chemical reaction that results in heat, light, and change in odor, then it would be considered a chemical change.
What type of chemical reaction often produces energy in the form of light heat or electricity?
synthesis
In a firework show the fireworks explode giving off heat and light is this a chemical change why?
It is a chemical change because the chemical composition is changed during this reaction.
Which layer produces heat and light for the sun?
The chromosphere produces the light and heat for the sun.
A dynamite explosion converts chemical energy into?
thermal enery cause it produces heat *and light and sound
