Why the environment is damaged when you leave a light bulb on?
Yes, leaving a light bulb will damage the environment because the energy used to light the bulb comes from a coal fired station and whilst the light is on, coal is burnt which releases carbon dioxide into the air which may contribute in global warming.
What powered the light bulb back in the 19 century?
In the 19th century, light bulbs were powered by electricity generated from sources such as coal, water, or gas. These power sources were used to create light by heating a filament inside the bulb until it produced light.
What are the three minerals in a light bulb?
The bulb is usually made of: Soft glass made from silica, trona (soda ash), lime, coal, and salt.
Coal has about 30E6 J of energy per kg but a power plant can only use 30 of this energy to make electricity (i.e. it is 30 efficient). How many kilograms of coal have to be burned to light a 100 W lig?
To light a 100 W light bulb, you need to generate 100 W of power. If the power plant is 30% efficient, you need 100/0.30 = 333.33 W of input power. Since coal has 30E6 J/kg of energy, you would need 333.33 W/30E6 J/kg = 0.0111 kg of coal to light the 100 W bulb.
Where does the energy for a light bulb come from?
The energy for a light bulb typically comes from electricity flowing through the filament, which heats up and produces light. The electricity is usually supplied by power plants that generate electricity through various means such as burning coal, natural gas, or using renewable sources like wind or solar.
Why did coal mining stop in the year 2001?
Coal mining has not stopped. I was inspecting an operating mine last week.
What are the 5 examples of chemical energy sources?
Fossil fuels such as coal, oil, and natural gas. Biomass from plants and organic materials. Hydrocarbons in gasoline and diesel fuel. Chemical reactions in batteries and fuel cells. Nuclear reactions in uranium and plutonium.
as black as coal?
(as) black as coal (as) black as coal Completely black; totally without light or color.
How does coal become light?
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
How long does a coal power plant produce energy?
A coal power plant can generate electricity continuously as long as it has a steady supply of coal to burn. The lifespan of a coal power plant can vary, but with proper maintenance and upgrades, they can operate for several decades.
How is light power made?
By burning coal
What is the transparency of coal?
Coal is considered opaque and does not allow light to pass through it easily. This lack of transparency is due to the high carbon content and various impurities present in coal, which absorb light rather than allowing it to pass through.
