Three common sources of heat that may cause a fire include electrical malfunctions, open flames (such as candles or gas stoves), and sparks generated by grinding or welding tools.
The three elements of the fire triangle that must be present are Heat, Oxygen, and Fuel. This has recently been changed though from the fire triangle to the fire tetrahedron. This includes Heat, Oxygen, and Fuel as well. But, it also contains a fourth, chemical reaction.
A heat source can cause a fire by heating materials to their ignition point, where they release flammable vapors that can ignite when exposed to the heat source. This process is known as combustion, and it requires a combination of heat, fuel, and oxygen to sustain the fire.
The three components of fire are heat, fuel, and oxygen. Heat is required to ignite the fuel, while fuel provides the material that sustains the fire. Oxygen is necessary for the combustion process to occur.
For fire you need three main ingredients. First you need a fuel, this fuel can be anything that burns like wood for example. Second you need oxygen, without oxygen a fire cannot burn. Finally you need heat, even though fires give off heat you still need it to start a fire. If you remove any one of these three ingredients then the fire will die.
Fire requires three main components: fuel (such as wood or gas), heat (to reach the ignition temperature of the fuel), and oxygen (to sustain the combustion process). When these three elements come together in the right proportions, fire can be produced.
Sunlight, fire, and pee
The three natural sources of heat and light are the sun, fire, and lightning. These sources provide heat and light through processes such as nuclear fusion, combustion, and electrical discharge.
The two major sources of radiant heat in a fire are the flames and the hot surfaces of burning materials.
All heat sources. Plus extreme cold sources cause burns.
Fire, Sun, and lights.
The sources of fire include heat, fuel, and oxygen. These three elements must be present in the right proportions for a fire to ignite and sustain itself. Heat provides the initial energy to start the combustion process, fuel serves as the material being burned, and oxygen enables the chemical reaction to continue.

Two sources of heat are the sun and fire. The sun emits heat and light energy through nuclear fusion in its core, while fire produces heat through the rapid chemical reaction of burning materials.
fire for heat,light and sun for light.
Wood and coal fire :)
