You start brainstorming!
List everything you can think of that would be affected by no heat or light. You should have a long list! Think of your own life and the lives of other people, too.
Now, write a story about people whose lives are like that - you'll have to use your imagination.
Fireflies are remarkable in that they produce light without also producing heat. All of their energy resources are used very efficiently to make light energy without wasting heat energy.
Without light and heat Earth would be a dead and frozen planet
Heat can not produce light without heating a certain object or material meaning heat by itself cannot produce light on its own.
Light and heat are the same stuff; electromagnetic energy. The difference is in the wavelength of the energy; heat has longer wavelengths than light. (It's all one broad spectrum from radio to heat to light to x-rays to gamma rays to cosmic rays; all electromagnetic energy.
Fire
luminous
fire
The old saying "there is no smoke without fire" tells you the whole story really. The formula is: FIRE + SMOKE ------> BURNING + HEAT That's all there is to it.
light emitted by a substance without combustion or perceptible heat.
how are heat an light and mechanical energy produced whoever wrote this you need to answers the question not write the question
Actually light and heat is one of the most important things we get from the sun which fosters life on earth. Without light plants will not carry out photosynthesis and ultimately they will die. Heat keeps our earths temperature warm otherwise the earth will freeze.
all plants and trees will die people cant survive without heat and light we cannot survive we will freeze to death
