Because the tungsten filament is evaporating. As the filament becomes thinner, resistance and temperature become higher, evaporation speeds up. Eventually the filament becomes so thin that it melts.
A 100 watt incandescent light bulb radiates 98 watts of heat and 2 watts of light. In summer, it takes 50 watts of air conditioning to get rid of the 98 watts of heat. A 20 watt compact fluorescent produces the same 2 watts of light while consuming 85% less electricity, and absence of heat makes it last ten times longer.
No, magnesium will not burn with a brilliant white light if heated above 100 degrees. Magnesium needs to reach its ignition temperature of over 600 degrees Celsius to produce a bright white light during combustion.
In theory, dark candles should burn faster, as dark light absorbs more heat than light colours, as light colours reflect more (which is why you can distinguish between dark and light colours). If the candles are made from identical wax, the dark colour should burn faster, as it would get hotter. However if it's different coloured wax it's most likely that the different wax has different properties which could change the difference in time.
Yes, carbon can burn in the presence of oxygen to form carbon dioxide and release energy in the form of heat and light.
Oxygen is typically needed for a substance to burn. It combines with the fuel to undergo a chemical reaction that produces heat and light.
When fuels burn in oxygen, carbon dioxide and water vapor are typically released as byproducts along with heat and light energy.
they only burn when you light them on fire !
The moon does not burn out. It reflects light from the sun.
you burn weeds by putting them in a pile and then light some fire

Both a tan and a burn result from exposure to ultraviolet light.
The answer to your question is yes you can het sun burn from reflections of snow, but its a combination of the sun and the reflection that gives you the sun burn. sun light is sun light yes uv light is reflected and will burn you
You probably have a light bulb burn.
Light bulbs burn out due to the filament inside them breaking or wearing out over time, which interrupts the flow of electricity and stops the bulb from producing light.
You forgot to light it?
You light it on fire...
Burn it
No. The legends only include a vampire burning in light.
