how thermal energy is generated?

In the laws of thermodynamics, it is stated that energy can not be created nor destroyed, but may be converted from one form of energy to another.  So, it might be better to ask how does one convert various forms of energy into thermal energy?\n\nWell, in the world of HVAC, we can burn a hydrocarbon fuel such as oil or gas (energy), and the products of the combustion process will be heat energy, light, water vapor, carbon dioxide, carbon monoxide (we try to create very little of this stuff), and vaporous and particulate matter (smoke .. again, we try to create very little of this stuff too).  The heat and light energy can be placed next to, or mixed within substances that have a lower temperature, and thus heat energy will flow from the hotter products of combustion to areas and substances that are cooler (heat energy always travels from areas of higher temperature to areas of lower temperature).  If a heat exchanger is used, the above products of combustion will be on one side of the heat exchanger, and substances such as cool air or relatively cool water will be on the other side, heat energy will flow from the hot products of combustion to and through the cooler heat exchanger material, and then will flow from the heat exchanger to the even cooler substance your trying to heat such as the water or air.\n\nElectrical energy can be converted to heat energy (thermal energy) by passing a current through a device that has resistance (a resistor).  It takes electrical pressure (voltage) to push the electrons through a resistive material, but any flow of electrons through the resistive material will cause the material to heat up.  The formula P = I x E applies here and “P” will be the rate of power measured in watts, “I” stands for flow of electrons measured in amps, and “E” is electrical pressure measured in volts.  To convert watt hours to BTU's (a watt hour can be a watt that is running for one full hour), you multiply watt hours times 3.413 (I have seen conversion factors ranging from 3.412 to 3.415, I’m not sure what the exact conversion is, but any number in this range will be pretty accurate).\n\nThere are other ways of converting other forms of energy to heat energy, including mechanical energy (friction), other chemical reactions, solar radiation, nuclear reactions  etc.

1. melting point\n2. expand to occupy the entire volume of the closed container\n3. thermal energy is a measure of the average kinetic energy of the particles also known as temperature.\n4. sorry - I don't get the question

It would be heat and sunlight- A cycle means that a substance or energy will eventually return to its origin.  Sunlight generates heat and chemical energy on the Earth, but is non-cyclic, in other words, you have to have a constant infusion of it all the time, it doesnt recycle.  The majority of the energy of sunlight is lost as heat, out of our atmosphere into space, never to enter the cycle again. So the flow would be sunlight in, some chemical use and some heat absorption, and eventually all the energy is lost as heat out.

what's the heat source?

heat is a manifestqtion of every kind of energy. Energy comes from movement of particles.  \nIn physics, heat is defined as energy in transit.[1] Generally, heat is a form of energy associated with the motion of atoms, molecules and other particles which comprise matter. Heat can be created by chemical reactions (such as burning), nuclear reactions (such as fusion taking place inside the Sun), electromagnetic dissipation (as in electric stoves), or mechanical dissipation (such as friction). Heat can be transferred between objects by radiation, conduction and convection. Temperature, defined as the measure of an object to spontaneously give up energy, is used to indicate the level of elementary motion associated with heat. Heat can only be transferred between objects, or areas within an object, with different temperatures.

for a window fan, \n\nelectrical energy is input and transformed into mechanical energy, plus there is a heat loss.

A good place to start will be to look at the following websites \n\nThermal Energy and States of Matter\nhttp://www.pschweigerphysics.com/thermenergy.html\n\nThermal Energy\nhttp://sol.sci.uop.edu/~jfalward/physics17/chapter6/chapter6.html\n\nThermodynamics and Thermal Physics guides\nhttp://physics.about.com/cs/thermodynamics/\n\nIf your doing a project you might look into "Ocean Thermal energy conservation" as a topic.\n\nOcean Thermal energy conservation is used to generate electricity using the temperature difference of seawater at different depths

Basically energy derived from steam or heat escaping from deep underground.  Kinda like harnessing "Old Faithful".\nHTH

Thermal energy is kinetic energy due to disordered motions and vibrations of microscopic particles such as molecules and atoms.

Almost all power plants use some heat source (coal, natural gas, nuclear pile, geothermal heat, concentrated sun rays) to generate steam. The steam turns turbines. The turbines turn generators.\nGenerators generate electricity which is where electromagnetism comes in. A simple model is this: when you move a magnet around a wire you see a current induced in the wire. Now a generator moves a whole bunch of coils of wire around magnets (or moves magnets inside lots of coils of wire) and thus uses electromagnetism to generate electricity.

there are 2 ways:\n1. using a thermocouple u will generate a potential difference. but the thermocouple will not generate much current so the power will be small.\n2. this is a classical method. a steamengine coupled to a dynamo.

Heat energy.\n\nThere is water (or a water mixture) cooling the core directly.  This water is radioactive.  You then have coils running in the water which have other water (protected from the radiation) coursing through them.  This water gets the heat transfered to it and turns to steam.  The steam runs turbines that turn a magnet core in the center of a copper coil that in turn produces electricity.\n\nHope this answers it for ya, feel free to email me!

Electricity is a form of energy.\n\nIt can be generated from other forms of energy, for example, chemical energy (burning fuel, or a battery), mechanical energy (a windmill), nuclear energy (atomic fission reaction like in a power plant).\n\nIn a battery electrical energy is converted from the  potential energy stored in chemicals which is released when they combine.\n\nIn a fuel cell, chemical energy is released in another type of chemical reaction.\n\nNuclear plants, windmills, hydroelectric dams or burning fuel in a generator turns a turbine or motor which moves a coil of wire through a magnetic field which produces energy.\n\nIn thermoelectric energy, heat is turned into electricity when two different metals are heated.

A thermal power plant uses heat.  I don't know what a 'themal" power plant is.  If you can't operate a spell-checker, I doubt you have the gray matter to expend on thermo-dynamics.

I understand you assume energy can be produced from heat. You are correct, however don't forget that -24 Celsius is also a "level" of heat energy (temperature in better words). In case you can find a substance that will expand substantially under -2 degree celsius. Then when you store this substance in arctic conditions, it will become pressurized and that pressure can easily be used in for example turning some turbine blades. Any kind of energy can be converted into any other type of energy, given necessary technology...
