Want this question answered?
no,it is made by artificial
the brightness of an object is the amount of light it reflects, the more it reflects the brighter it will be. Or the object could be giving out light, a vehicle head light for example
light and thermal energy
The sun, as it's a star just like the others, is already exploding, its light and heat comes from constantly exploding Helium gas, spread all over it.
Light bulb
Exothermic Change
The principle is based on chemical reactions.
chemical change
A chemical reaction (combustion of gunpowder); Newton's laws of motion; the varying spectrums of transition metal compounds.
Sound energy, light energy are forms of exploding fireworks. Both are released during explosion.
You can observe colorful light emission in fireworks and in different sorts of chemicals as in Lithium it turns green when heated.
You get to a level that allows you to light fireworks. I think its for goldpandas
It's a exothermic reaction because heat and light is being released.
It depends on where you live. If you would like to know for a specfic state or city, please enter that when you are asking this question. For example, enter, "Can you light off fireworks on July 2 in Tampa FL?" and it will be easier for us to answer.
It is a chemical change because the chemical composition is changed during this reaction.
notrealy because many people light fireworks its not a big deal
They light firecrackers and fireworks.
