i am definitely no expert as I'm in grade six, yet i think that it is artificial because the fire (natural as it is) is created by the chemical reaction when the box and match are struck together, therefor, quite unnatural in my opinion. You don't need to quote me on this, to gather your own opinion just think about if a match would work and even exist if we didn't exist either!
-TvGaming, your welcome if it helps ;D
If you lit a hazelnut on fire, it would undergo combustion, producing flames and releasing heat. The nut's outer shell and oils within would contribute to the burning process, resulting in a small, relatively short-lived flame.

Energy cannot be saved.!!!!
However, physical or chemical sources can release more or less energy as appropriate.
This release is then transferred ( the energy) to another form/source.
net calorific value and gross calorific value
GCV to NCV conversion:
- Using the following IPCC formulae determine the NCV of those fortnightly samples
- NCV = GCV - 0.212H - 0.0245M - 0.0008O
- Where H - Percentage of Hydrogen, M - Percentage of Moisture and O - Percentage of Oxygen (as determined from the ultimate analysis report)
- Please note that here GCV and NCV are in Mega Joule/kg, therefore it is required to do the necessary unit adjustments (1kcal/kg = (4.186/10^3) = 0.004186 MJ/kg)
Assuming GCV = 18.4017MJ/kg, O =9.23%, H = 3.63%, M=7.45% (Source: Coal analysis report conducted independent testing laboratory - ' National Council for cement and building materials')

Petroleum is a fossil fuel. Fossil fuels have many disadvantages:
One is that we use fossil fuels for like running our cars and providing electricity. So we use them for important things, but one day we will run out of fossil fuels and we will have to find replacements. In some places they do use things like windmills and water generator for electricity, but most places rely on them.
Another is that using fossil fuels is bad for the environment, and the pollution is causing global warming and climate change.
Plants use the ribosomes in their cells to store energy not needed at that time.
Extermination of the human race or peanuts.
Algae fuel is any fuel made using algae. Algae are a type of simple organism, of which most are photosynthetic (they get their energy from the sun). The smallest algae are unicellular, the largest are the seaweeds that make up kelp forests.
Some types of algae use sunlight to make oil, and if these algae are harvested and the oil extracted from them, the oil can be used in a variety of ways, including as a replacement for petroleum derived diesel fuel.
Whatever portion of the algae which is not oil, is carbohydrates and proteins. These carbohydrates and proteins can be processed to produce butanol, a oily, energy-dense alcohol, which can be used as a direct gasoline substitute.
The oil from algae can also be converted (using the same processes that are used on petroleum) into other types of fuel, such as biogasoline, and aviation biofuel.
The non-oil components of algae can also be converted to other fuels besides butanol (although that's one of the most valuable producable fuels), such as methane and ethanol.
Corn is an excellent source of vitamin B1, B5, C, E, folic acid, magnesium and phosphorus. It is low in protein, due to the minimal content of the amino acids lysine and tryptophan. Corn is a good source of complex carbohydrates, fibre, and healthful essential fatty acids. Nutritional energy would be the word you are looking for.
To make a working model on energy resource and conservation there are several steps. The first step is to make a propane wheel. The second step in this model would be to attach piping to six containers and create a circle with these containers. The bottom of all six containers should be submersed in water. Lastly, fill all of the containers with propane
If no, or few, applications are left up and running a computer will not consume much power when left on. Computers in general consume less power then a single light bulb when running. At idle they may go down to as little as 30 watts depending on age, speed and configuration of the computer.
Voltage does not run through power lines. If it did, then birds would be killed instantly
as soon as they sat on a power line.
Voltage is the difference in potential between two things. In the case of power
lines, it may be between the two wires in an extension cord, or between one wire
and the Earth. The bird is fine, because both of his feet are on the same wire, and
there's no difference in potential between them.
The utility lines that enter your house measure 110 volts, 220 volts, or 480 volts
compared to the Earth. When you plug a lamp, a cellphone charger, or a radio into
an ordinary outlet in your house, there is typically 110 volts between the two prongs
of the plug.
The primary line that runs down the street along the very top of the poles measures
2400 volts, 4800 volts, or 7200 volts compared to the Earth.
The heavy cables that carry power from the generating stations to the distribution
substations, or intercity along the large transmission towers, measure several tens
of thousands of volts compared to the Earth.
The Energy Star certification comes with the appliance from the factory. If it passes all tests for efficiency, it is Energy Star Rated. If it doesn't it isn't. You can't get an Energy Star rating for an appliance that left the factory without one. It isn't something that can be bought, it can only be earned.
of course it does, you don't use the energy to keep it running, hence, you save energy.
A generator can produce energy if a CME occurs. A transformer could blow and cause your power to go out. but they both have something to do with power and energy.
With a generator mounted on the "turbine". The propeller spins the generator shaft.
You can conserve energy by using fans instead of air conditioners, as fans require much less energy to operate than air conditioners.
aaah! bcoz it's concrete!
When you use less electricity or less gas in your car, you are saving energy. The importance of saving energy includes reducing air pollution, saving money, and reducing Greenhouse gas emissions.
Metals are inorganic, they don't decompose. They might change form by bonding with other elements (e.g. rusting) but metals don't "decompose".
