Heat energy emerges from behavior of atoms in a body and it can be quantified through temperature scale. Cheshire explains that atomic motion results in heat energy and possessed energy defines temperature (13). In addition, heat energy spread in an environment based on temperature gradient and moves from regions with high temperatures to regions with low temperatures, a definition that is consistent with Sang’s classification of heat as an energy transfer (81). Mechanism of heat also identifies and relates to the principles of motion and conservation of energy. Based on energy conservation law, energy cannot be “created or destroyed” but may be converted to other forms (Chesire 25). Newton’s first law of motion however explains that a body maintains its velocity unless an external force acts on it while Newton’s second law explains that force (and by extension, energy) is proportional to kinetic energy (Giordano 40, 41). Consequently, atoms in a body will continue to move at a constant aggregate force and retain the body’s heat energy unless an external force converts energy in the body, positively or negatively. Example of a change is converted energy into a body that would increase velocity of atoms to increase heat energy in the body.
Laws of thermodynamics explain the relationship between heat energy and mechanical energy. From the second law of thermodynamics, mechanical energy can be converted to heat energy while the third law of thermodynamics explains that heat energy can be converted to mechanical energy (Giordano 535). Mechanical work can therefore yield heat energy and heat energy can be converted into mechanical energy for doing mechanical work.
Direct heat transfer from a body or into a body occurs through conduction, convection, or radiation. Conduction is the heat transfer through movement of atoms from hot to cold regions and is common in metals in their atomic states and in ionic compounds. Convection is another

This paper shall discuss the thesis that the socio-economic benefits of using renewable energy resources should be considered a sufficient ground in motivating the U.S. government to financially support the development of renewable energy resources such as solar, wind, water, and geothermal energy throughout the United States.
Environment comprises of both biotic and non-biotic issues that have control on organisms (Anil, 27). Non-biotic factors like light, heat, water, and distinctive gases merge with biotic factors (all adjacent living genuses). Environment habitually changes over time and therefore, numerous organisms have the aptitude to acclimatize to these changes.
Guided by those who have set out on similar journeys, I have grown increasingly aware of its ever-changing impact across the globe and intermingled nature of such an impact with peoples' health, their lifestyles and their daily activities. Writing about global warming can be a daunting task.
While many other politicians, thinkers, and analysts may believe that the world is overwhelmed with other threats and concerns, the issue of global warming should have a priority because it has the potential of affecting the whole world, not just a country, a region, or even a continent.
It is indeed true that the usage of fossil fuels offers many advantages (Borowitz, 2004). First and foremost the fossil fuels happen to be easily accessible. Fossil fuels are found in abundance on the planet earth and can readily be extracted and used to meet the human energy needs (Borowitz, 2004).
For close to twenty years, the government of Finland has aimed at producing as much electricity as it can through the combined power plants and heat popularly known as CHP. In this regard, Finland ranks among the
The temperature of the planet stays stable when there is an energy balance between how much shortwave radiation emitted by the sun is absorbed by the earth and then how much long wave is reflected back in the space.
increase in the amount of greenhouse gas emission in the transportation industry requires strategies for reducing consumption of fossil fuels as a source of energy in the transport industry. In order to reduce the amount greenhouse gas emission, a number of necessary changes
Chadchan and Shankar (2009) noted that the fastest growth in urbanization started in the 20th century, and the trend was mostly notable in the third world countries. Migration from rural to urban areas occurs
The author states that the smoke from mills, factories, electricity plants and other installations which emit green-house gases emissions are severely harming the natural weather pattern and system as well. Fuel combustion which normally takes place in cars and other motor vehicles is also causing damage to the natural environment.
