Why is fire striking a match an artificial source of light?

User Avatar

Asked by Wiki User

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!

What would happen if you lit a hazelnut on fire?

User Avatar

Asked by Wiki User

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.

What are the best ways to save energy?

User Avatar

Asked by Wiki User

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.

NCV and GCV of coal?

User Avatar

Asked by Wiki User

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')

What are the disadvantages of using petroleum as fuel?

User Avatar

Asked by Wiki User

(Another contributor wrote:)

Petroleum is a fossil fuel. Fossil fuels have many disadvantages:

  1. They add carbon to the atmosphere, causing global warming.
  2. They are very limited in quantity and become more expensive to find and refine.
  3. They are biologically hazardous and can pollute ground and water

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.

How can algae be used as a fuel source?

User Avatar

Asked by Wiki User

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.

What energy is being tranferred when a chicken eats corn kernals?

User Avatar

Asked by Wiki User

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.

How do you make energy resources and conservation working model?

User Avatar

Asked by Wiki User

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

How much energy does the energy-efficient computer save?

User Avatar

Asked by Wiki User

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.

How far can electricity travel in water?

User Avatar

Asked by Wiki User

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.

Where do you get the energy star certification for appliances?

User Avatar

Asked by Logansnana

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.

Asked by Wiki User

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.

What can you use instead of air conditioners to conserve energy?

User Avatar

Asked by Wiki User

You can conserve energy by using fans instead of air conditioners, as fans require much less energy to operate than air conditioners.

Why is energy conservation good for your environment?

User Avatar

Asked by Wiki User

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.

How long does metal take to decompoes?

User Avatar

Asked by Wiki User

Metals are inorganic, they don't decompose. They might change form by bonding with other elements (e.g. rusting) but metals don't "decompose".
