Describe the laws of thermodynamics - Essay Example To understand energy better, there has been that study called thermodynamics that seeks to study and understand the various forms of energy. First, energy has been defined as the capability of perform some duty, the ability to bring change. Therefore, in order to understand the thermodynamics, there have been laws established. These laws try to explain how heat also called Thermo travels through other forms hence the term thermodynamics. As such thermodynamics connotes the different character of heat (Bub, 2001, p. 570). Under the first law, Zeroth Law, we are made to understand that if three bodies are at equilibrium, then they would have the same character. For instance, three bodies under similar conditions would have same temperatures in a matter of time. The second law, First Law is understood in the context that some form of energy may be at rest and would be changed if some other force is applied to it. Then we have the Second Law, which seems so difficult to comprehend. It behaves differently under different circumstances (Bub, 2001, p. 572). Lastly, we have the Third Law, which states that there are some things that are totally hard to change for instance cooling something to a particular degree. It is definite that there would be some factors to affect the targeted temperature basing on the already mentioned laws. From the above, it is now important to state the different types of energy. These include fossil fuels, solar energy, nuclear energy, wind power, hydropower, and bio-fuel. All these types have their good and bad sides. With fossil fuels, it is easy to establish the plants and extract. They provide efficient and cost effective energy, and they can be located anywhere. Fossils are also easy to find and cheap to extract. However, they are so much of pollutants that they threaten the environment. Harmful gasses emerge from minerals causing the destruction of the atmospheric layers. Further, by getting them from the earth,
