The first law of thermodynamics is mainly concerned with energy conservation and it states that energy cannot be created or destroyed. However, energy can be converted from one form to another. The total amount of energy entering into a system must be equal to the equal to the total amount of energy that is leaving the system (Toja-Silva & Rovira, 2014). Energy can be transformed and transferred but it must always remain constant.
The second law of thermodynamics is entropy. Entropy is the measure of change from order to disorder. Matter will move from an area of high concentration to an area of lower concentration. The law states that entropy of an isolated system that is not in thermal equilibrium will increase to a point of equilibrium (Toja-Silva & Rovira, 2014). It is not possible for heat to emanate from a cold object to a warm object without work. In essence, an object that is cold cannot make another object warm naturally.
Energy remains constant because it cannot be created or destroyed. The first law mainly covers the conservation of energy and its transformation from form to another. However, something does change in the energy conversion and that is its re-usability. Anytime there is an energy conversion there is some energy that becomes less useful and eventually, all the energy will become less useful. This is mainly in as far as the ability of energy to make things happen is concerned. Therefore, the more energy that is used the more low-grade energy is available. Low-grade energy is only useful for warming the air around us and it cannot be used to do things that are considered useful. With energy efficiency, we would be able to reduce the amount of low-grade energy. Thus, ensuring that we are not...

History Of the First and Second Laws of Thermodynamics Modern life would not be the same without two important laws of thermodynamics. Without these two laws we would not have the gasoline engine or electricity in our homes. These two laws made the inventions that we take for granted possible. These two laws are the first and second laws of thermodynamics. The first law of thermodynamics is that energy can neither
Thermodynamics Research Lack of access to potable water or in places where it is hard to get is a reality that many individuals encounter. Technology is capable of assisting in improving this particular situation. An example of such technology is reverse osmosis; this procedure utilizes membranes to separate salt from seawater. It applies pressure vessels that house three membranes that are frequently spirally wound. Around 35 to 50% of water (potable)

Photosynthesis 1231 Plant Cell and Solar Cell: Similarities and Differences Photosynthesis is that process by which plants harness the solar energy for producing food. These cells help the plants to trap energy from the daylight. This trapped light is converted into other constituents that are then used by the plant to manufacture food. The additional components such as oxygen are released to the atmosphere. After these processes, the light energy is converted
This is frequently referred to as entropy. In the route of energy transfer, some energy will disperse as heat. Entropy is a measure of disarray. The course of energy sustains order and life. Entropy is successful when organisms stop taking in energy and die (Laws of Thermodynamics, 2010). Many experts feel that Hydrogen is the ideal fuel known to man at this time. It is a fuel source that has
Photosynthesis is the process by the help of which plants make their own food by capturing the solar energy. Solar cell as compared to the plants coverts the sunlight into electric energy in order to be used by the human beings. This paper aims to highlight the differences and similarities between a plant cell and a solar cell in addition to the application of laws of thermodynamics to each system. Laws
