Energy

Parent Category: Science
The Energy category covers the description, definition, and use of all types of energy. Questions of a general nature can be put in the general Energy category. Other sub-categories exist for Fossil fuels, Nuclear energy, and renewables such as Wind, Solar, Hydro, Tidal, and Wave power.
It has chemical energy which can be released when it is burned. Itmay have gravitational potential energy if it is in a positionwhere it can fall. It will also have kinetic energy if in motionsuch as a paper airplane.
If you're talking about wind power, then yes. Wind power is a renewable source of energy because wind is anatural, re-usable source. Wind power is generated by windturbines . To put it simply, the wind turns the blades, whichspins a shaft, which connects to a generator, making electricity.The...
Usually we use a mechanical or electrical meter. Gas supplies cansimply drive round a counter. Electricity can be measured inseveral ways, for instance by using part of it to turn a disc whichin turn drives a counter. Essentially we measure how much power weuse and for how long. The unit is usually...
Greenhouse gases, climate and temperature can all be affected byenergy conservation.
According to an internet search, about 30% of the world's crude oilproduction comes from offshore rigs.
One disadvantage for wind power is that it takes a lot of money tobuild an actual wind turbine. You could also talk about the spacethey take up which could be used for agriculture or housing.
Geothermal power can be used in our homes as air-conditioners andheaters. It is renewable as the Earth is constantly making heat.
The sun gives off a few billion wats per second. If solar power went mainstream, then the world would be set on energy for the next billion years until the sun explodes.

Conduction, convection and radiation. Conduction is when heat is transferred directly between materials. convection occurs when heated materials move from one place to another heating matter along the way. Radiation is when waves of heat move through space.
The hydrocarbon molecules in petroleum contain a large amount of chemical energy. When they are burned, two things happen: they release a lot of that energy as heat, and they release gases (carbon dioxide, water vapor and sometimes nitrogen, depending on the fuel). The heat energy may be used...
There are some very deep sources of radiogenic heat with geothermalpower potential, like the Cooper Basin in Australia which lies 4.2kilometres or over 2.5 miles underground. In other places in theworld heat is harvested very close to the surface like The Geysers,a geothermal field in California.
As the material body travels at the speed of light its relativisticmass becomes infinite. Hence the kinetic energy too becomesinfinite which is not practically possible
I don't want to avoid the question, but it is something like askinghow big a lake is. Some are tiny and some enormous. Similarly, youmay be asking about a small windmill on an farm in Lancaster, PAproducing kilowatts or a large "wind farm" that connects to theeast coast power grid and produces tens...
Yes, we are running out of Fossil Fuels. In about 30 years, it will be gone. We will have to turn to solar and nuclear energy.
Clouds . Particles in the atmosphere . Oceans . Snow and ice Part of the solar energy that comes to Earth is reflected back outto space in the same, short wavelengths in which it came to Earth.
It depends on many factors, such as weather conditions (how muchsun there is in the specific time, which can also be affected bywhich hemisphere you're in). Speaking generally, solar panels havelow energy density (many are needed for a significant amount ofenergy.) But after the initial buy, it's...
Lignite is the type of coal that is stage 2.
There are many factors involved, such as age, load, type of power,capacity, and environment. For instance, the average cost of just fuel in a typical nuclearpower plant is around $40 million (US) for 18 months. The maintenance of a power plant includes parts, labour and oveheadfor breakdown repairs,...
energy can not be lost it can only be transported into other things
Heat is transferred in three ways - radiation, conduction andconvection. Radiation is caused by the movement of heat waves.Conduction is when heat is transferred by direct contact betweentwo items. Convection is when there are differences in temperatureand density causing the movement of molecules.
1. It is very 'clean' - there aren't by-products. 2. It is renewable and as a special... 3. It is free
The Iron lung was essentially a pressure chamber in which thethe pressure could be increased quite a lot over atmosphericpressure as a means of forcing the absorbed coal gas back out. Itsother common use was in treating polio, and also divers with the'bends'. . +++ . Coal-gas is poisonous by being...
who invented conductors
Molecules that are in a solid are constantly moving around andvibrating. All states of matter possess molecules in them.
1. High energy density - a lot of energy with not much fuel 2. Can be used directly in home 3. Cheap compared to other forms of energy as an extra 4. Relatively easy to transport
Treatment of erythropoietin disease
Many energy sourcescommonly used by humans are forms of chemical energy. They areusually labeled "fuels." The way to use the chemical energy in mostfuels is by burning them, as we do with wood, natural gas, gasoline , coal , and others..
Advantages of Non-Renewable Energy Because non-renewable energies seem abundant, like oil, gas andcoal, some experts believe if channeled correctly, our supplieswill be safe for future generations. Non-renewable energy sourcesinclude oil and petroleum products, gasoline, diesel fuel, andpropane,...
we should turn off the lights because it decreases your electricity bill, reduces our energy use and you don't have to keep on buying new light bulbs when old ones run out from you leaving it on
Yes, it is. A typical toaster heats food by radiation fromelectrical heating elements. Most of the energy is invisibleinfrared radiation, although visible red light is also emitted.
Solar cells (also known as photovoltaic cells) are made of solarcells. To be more specific, they are made of slices of asemiconductor with a metal layer.
Holding a cup of boiled water the heat from the liquid will make the cup hot itself. An ice cube melting in your hand because the heat from your hand was conducted to the ice cube. Metal and electricity are very good conductors, wood is a horrible conductor. Hope that helped (:

Some are studied and put in museums and the certain fossils are now oils and natural gases
The energy given out by the sun is constant and free of cost makingit renewable. Say for instance you have a litre of petrol, at theend of its use it does not replace itself, its gone forever unlikethe suns energy.
There is a finite supply the world around us continues to circulate energy. Beneath us the earth is heated so it will always produce energy from the heat. Geothermal persay! Look that word up, it really helps.
Thermal pollution is usually associated with increases of water temperatures in a stream, lake, or ocean due to the discharge of heated water from industrial processes, such as the generation of electricity. Increases in ambient water temperature also occur in streams where shading vegetation...
They can't. Fossil fuel is made from fossils millions of years ago. Renewable has to happen much sooner than that.
Wind like waves and sunlight are created by natural functions of the earth as a planet. They do not require time to form a fuel like coal and gas. As these functions are "naturally occurring" they are considered to be renewable. They will, as far as we are currently concern always going to occur....

Hydroelectric power plants generate electricity by the action ofthe "falling" water spinning a turbine which rotates a wire insidea big magnet.
Major draw back for Solar energy especially in Photo Voltaic type is the cost. With progress efficiency, the cost per unit still keep rising. A solar thermal plant in alternative can be made at reasonably cost competitive but was limited to economy of scale to be in a large size. Both Photo Voltaic...
Yes, the denser the cloud of water vapor, the more solar energy isblocked, or more accurately "reflected" back into space.
Yes. Sound energy is a carrier of energy.
Different materials boil at different temperatures (generally andvery roughly speaking, for similar molecules the lighter they arethe lower the temperature at which they boil). By raising thetemperature enough to boil the lighter components of a mixture butnot enough to boil the heavier ones, the...
That's not QUITE what it does, or at least it's not ALL of what itdoes. For similar compounds, in general, lighter molecules boil - thatis, become a gas - at a lower temperature than heavier ones. "Cracking" is the process of splitting large, heavy molecules intosmaller, lighter ones. Because they...
Isomerisation causes straight chain alkanes to become branched alkanes which prevents the chains from moving to close proximities of each other. This reduces the van der Waal's intermolecular forces between chains so less energy is needed to overcome the forces and thus a lower boiling point.
OSHA, NFPA and EPA regulations specify what safety precautions must be taken at power plants. Also various state and local regulations must be considered as well.
The width of lightning is determined by the voltage.

Energy is typically stored as fat in an animal, however it is present in muscle and many other tissues. But fat is the main "storage" form of energy in an animal.
fossil fuel is not edible so you cannot use it for cooking. But the heat energy generated on combustion of fossil fuel can be used for cooking. 575tur6 . Gas and coal and oil, in various parts of the world.
It doesn't occur in nature. It occurs as a long chain hydrocarbon,such as crude oil. Crude oil is then split up into differentfractions in a fractioning column (via distillation). One of theshorter chains that has practical uses is petrol. Fractions include: Fuel oil, Diesel, lubricating oil,...
If you mean energy produced by nuclear reactors, then "heat" and"light" would be the answers (Just think of the sun)
uranium is put in a nuclear reactor and the atoms in it are splitapart creating enormous amounts of heat.the heat is then used toboil water creating steam and turning turbines creating energy[electricity]
A battery and the human metabolic system are examples of uses of chemical energy but there are way too many uses to list here!

Crude oil is the oil in tankers or pipelines going to refineries. It is a complex mixture of compounds. Now, all plants need to breath. A plant that is covered in oil and that cover is maintained, will likely die. This can happens when a oil storage tank leaks. The environmental damage can be...
Coal is abundant and easy to convert into electricity.
No, nuclear power is a decent source of energy, depending upon thereactor design and siting. Locating reactors over fault lines ornear ocean shore lines seems unwise.
Birds have a proportionally greater surface area within the lungsfor oxygen intake during flight. Birds that are frequenthigh-fliers also have hemoglobin with a higher oxygen affinity,allowing for better oxygen transfer. The capillaries of birds arealso more efficient, keeping oxygen delivered to...
South Africa has very few large rivers that flow through-out the year. Therefore, hydroelectric power stations is not the most suitable solution. South Africa has rich coal deposits and is also a prime candidate for solar electricity.
