What is the difference between solar energy and photovoltaic energy?
Solar energy is heat the sun delivers to a surface. Photovoltaic energy is electrical energy a cell or group of cells delivers, in Volts and Amperes, to a load.
Name three things that are gas?
Main Gases:. Nitrogen. Oxygen. ArgonThere are many more but these are the main...
What are the main types of energy used in Sweden?
They burn trash/garbage to make electricity.
What is the main source of energy in star like sun?
Hydrogen fusion is the main energy source in any star.Put very simply, four Hydrogen atoms fuse to create Helium. The atomic weight of Helium is slightly less than four Hydrogen atoms the extra mass is released as energy.
What happened to Lost?
Well, thermodynamics is the science that studies this. According to the the first law of thermodynamics, all energy in all forms are conserved. The main types of energy we consider is kinetic, potential and internal energy. You may not be familar with Internal energy but it is another form of energy that we lump the energy of chemical bonds and kinetic and potential energies (ON THE MOLECULAR LEVEL) into it. Internal energy is proportional to the temperature of the object.
By what three main gases is heat energy absorbed in the atmosphere?
Water vapor, carbon dioxide and ozone.
What are the two principle absorbers of radiation emitted by earth's suface?
The two main absorbers of radiation emitted by Earth's surface are water vapor and carbon dioxide in the atmosphere. These gases trap heat and contribute to the greenhouse effect, which helps regulate the Earth's temperature.
What are greenhouse gases and how they are greenhouse gases?
Those gasses that allow the passage of shorter wavelength energy such as light but reflect or absorb longer wavelength energy such as heat. The main such gasses in our atmosphere are water vapour and carbon dioxide.
What items use heat energy.?
Cooking uses heat energy as the main source. It is the main activity that uses heat as a source of energy.
What is the main type of heat transfer in liquids and gases?
The main type of heat transfer in liquids and gases is convection. Convection occurs when heat is transferred through the movement of the fluid itself, carrying heat from one location to another.
What is the source of energy and heat?
The main source of energy and heat is the sun.
How is heat energy transferred between objects?
Heat energy is transferred between objects through three main processes: conduction, convection, and radiation. Conduction occurs when heat is transferred through direct contact between objects. Convection involves the transfer of heat through the movement of fluids or gases. Radiation is the transfer of heat energy through electromagnetic waves.
What gases in the earth's atmosphere reflect heat?
None. No gases reflect heat.Heat from the Sun arrives as short-wave energy and passes right through the greenhouse gases and heats the earth.This heat is emitted back up as long-wave energy. Long-wave energy is blocked by greenhouse gases, which absorb it and do not let it pass into the upper atmosphere and beyond.These greenhouse gases include:water vapor, the most plentiful gas,carbon dioxide,methane,nitrous oxide,chlorofluorocarbons (CFCs),hydrofluorocarbons (HFCs) andPerfluorocarbons (PFCs)Other minor gases might be included, as well.
What is the main fate of energy for most ecosystems?
The main fate of energy is for it to be lost as heat.
How do condensing boilers work?
Condensing boilers are designed to increase energy efficiency by using the wasted heat from flue gases to heat water up before it even reaches the main boiler. These boilers are very energy efficient and are mandatory or preferred in many countries.
How is heat energy transferred from the fire?
Heat energy is transferred from the fire through three main methods: conduction, convection, and radiation. In conduction, heat is transferred through direct contact between the fire source and another object. In convection, heat is transferred through the movement of hot gases or liquids. Radiation involves the transfer of heat energy through electromagnetic waves emitted by the fire.
What is the main energy source that drives global warming?
The main energy source for global warming is the sun. The warmth that reaches us from the sun is trapped by the naturally-occurring greenhouse gases, to maintain a comfortable temperature suitable for human habitation. The recent rise in greenhouse gases, resulting from human activity, causes more of the sun's heat to be trapped, resulting in global warming.
