No. That's one of the things that makes fireflies an object of interest in chemical research.
Yes it could. Haven't you ever noticed that when you keep your lamp on for a long time and you touch it, it is very hot. This is because inside the bulb there is a metal called tungsten (I am not sure if this is the correct spelling). When you heat up that metal to a certain point it starts glowing. Therefore light doesn't exactly produce heat but light produces heat depending on situation. that's it
Yes, all luminous objects are capable of producing light. This includes sources like the sun, stars, light bulbs, and flames. Luminosity refers to the amount of light emitted by an object.
Friction produces heat by converting mechanical energy into thermal energy. Light is produced by sources such as the sun or light bulbs. Conduction transfers heat through direct contact between materials. So, friction produces heat, light is emitted, and conduction transfers heat.
Light bulbs convert energy to light. This conversion is inefficient, meaning that not all of the energy will convert to light because of the design of the bulb and the laws of physics. The energy that does not become light is released as heat, and that's why a light bulb gets hot.
Light and heat are connected through radiation. When light waves strike an object, they can be absorbed and converted into heat energy. This is why objects appear warmer when exposed to sunlight, as the light energy is transformed into thermal energy upon contact with the object.
no
All these sources produce infrared waves, which we experience as heat.
Yes, most chemical reactions that give off light also produce heat. This phenomenon is known as chemiluminescence, where the energy released during the reaction is emitted as both light and heat. However, not all reactions that produce light necessarily produce heat, as some reactions can be endothermic and absorb heat instead.
No.Ligtning is not a heat source.Unless u think that the electric of the lightning have heat.<<Previous answer:Yes.Fire is a heat source and a light source. If you were meaning light bulbs, then yes again. The electric current flowing through the filament (excuse spellings) causes the wire to glow (creating the light) and generate heat. This is caused by the resistance in the wire. Even tiny little leds generate heat and light. I may be wrong here.... but I dont think any light source does not generate heat of some kind. Heat is light radiation in the near and far infra-red range. You can have light sources that generate very very very little infra-red light, for example flourenscent lights produce light in the visible range almost exculsively BUT yes all light sources do produce some heat as an unavoidable energy loss.>> Lightning is a heat source. It is electricity rapidly flowing through a column of ionized air. Thunder is the shock wave it generates in the atmosphere. Think of the crackling noise a static filled blanket makes. Move it in the dark and you can see the static letting go - like lightning in miniature.
Yes, light can be produced without heat in certain situations, such as with light emitting diodes (LEDs) or certain types of fluorescent lights. These light sources generate light through processes other than the generation of heat, making them more energy-efficient.
if you mean to have commas between heat, light, magnetism, and electrical charges then there is none. if heat light magnetism is all one thing then you're on your own.
If it is 1000 watts then it produces a 1000 watts. A watt is 1 joule/sec.
No, all planetary bodies only reflect light. Light is only generated by stars. This does not count artificial light or volanic light.
No. Part of the energy is wasted, mainly as heat.

Chemical reactions can produce heat and energy but not all chemical reactions produce them. Exothermic reactions produce heat and energy (possibly in the form of photons/light), while endothermic reaction absorb them.
All heat sources. Plus extreme cold sources cause burns.
