the objects which emit light of their own........example:sun,burning candle etc....,
The range of frequency of sound that coal trains emit when moving hovers around 20 Hz to 20,000 Hz
Objects that emit light are usually referred to as incandescent.
Burning coal is thermal energy. It can be used to produce mechanical energy.
Burning coal has chemical potential energy, because the energy is stored up in the bonds between the carbon molecules, and when the coal is burned, the stored energy is released and transformed into heat, light, and even sometimes sound energy.
Burning coal gives heat (thermal), light and sound energy.
By burning coal
Yes burning of coal is an exothermic reaction because energy is released in this process in the form of heat and light.
This process emits several classes of Pollutants, all of which are Air-borne Toxic Chemicals.
Actualy coal does not become light at all! Coal is commonly used as burning material to power something, but i guess people could burn it for light by lighting it on fire, yet the coal is just the fuel that is feeding the flame. Hope i helped :D
Oil, gas and coal burning always releases light or radiant energy. This is due to the high temperature of the burning material in the flame, it becomes incandescent.
Burning coal is an exothermic reaction as it give heat
Light bulbs emit light.
Technetium doesn't emit light.
Yes galaxies emit light
bulbs emit light
Bituminous coal is a soft coal, compared to anthracite coal, a hard coal. Bituminous coal is a long-burning, hot burning source of fuel.
