In nature, the flow of energy occurs in a closed efficient loop. This loop preserves the laws of conservation of energy “energy is not created or destroyed, but converted from one form to another”. The source of this energy is the sun whose energy trickles down to the consumers and back into the earth in an entropic fashion. Looking at an ecosystem from a physics and chemical perspective, the first and second law of thermodynamics is obeyed and preserved (first law of thermodynamics) (second law of thermodynamics). This utilization of Continue reading...

1.0 Abstract
The report is divided into two major sections. The first section of the report deals with a discussion about fundamental physical quantities together with their SI units. The quantities highlighted in the report include Mass, length, time, temperature and plane angle. A discussion of the derived physical quantities together with their units has also been presented in clear detail. The second part of the report focuses on providing a discussion of two machines that apply thermodynamics and are used in oil and gas industry. The machines identified to apply Continue reading...

Laws of thermodynamics:Energy is the ability to do work. In the universe, the energy exists in many forms like heat, light, etc. According to the first law of thermodynamics, energy cannot be created or destroyed. The amount of energy is conserved, and energy can only be converted into different forms. First law of thermodynamics is also termed as conservation of energy principle. (Kanoğlu, M., Çengel, A., & Dincer, I., 2012).
According to the second law of thermodynamics there exists thermodynamic variable called entropy, and entropy of an isolated system increases or remains constant with time. Entropy is the unavailable Continue reading...

The absolute temperature pertains to the temperature scale measured in kelvin where the zero on the Kelvin scale pertains to the theoretically lowest attainable temperature. This particular temperature scale was established after the observations of a phenomenon that at any given pressure, the plot of the temperature and the volume of a gas follows a straight line. Even with different pressures, the plot is always straight; furthermore, all plots seem to be directed towards a similar y-intercept which is -273.15 ˚C, that is, the temperature value when the volume is zero – or close to zero (Chang & Overby 144).
Theoretically, Continue reading...

Thermodynamics is a field of physics that deals with the transformation of mechanical energy into thermal energy or the transformation of health to work (Conserve-Energy-Future, 2013). The first law of thermodynamics states that there is internal energy increases and such is manifested by temperature increase or pressure increase or phase changes (Conserve-Energy-Future, 2013). When heat is changed into other energy forms, or when other energy forms are changed into heat, the overall amount of energy is constant. The second law of thermodynamics states that it is impossible for an engine unaided by outside energy to transpose heat from one Continue reading...

In your own words, describe the laws of thermodynamics.

First law of thermodynamics states that the total amount of energy is always conserved, and it can be only transformed into different forms.
Second law of thermodynamics states that the unavailable amount of energy of an isolated system either increases or remains constant over time.
Explain how these scientific laws apply to energy use, energy conversions, and the need for energy efficiency. Heat engines enable the heat energy to be transformed into kinetic energy through a medium of fuel. According to the first law of thermodynamics the engines convert heat energy to an equal amount of kinetic energy. But, Continue reading...

Thermodynamics is the study of energy, energy transformations, and relationships among heat, work, and energy (Farabee, 2001). There are four laws of thermodynamics: Zeroth Law, First Law, Second Law, and Third Law. These laws govern even our simplest daily activities.
According to the Glenn Research Center (2014), The Zeroth Law deals with temperature. It states that if object A is in thermal equilibrium with object B and if object B is in thermal equilibrium with object C, then object A and object C are also in thermal equilibrium, as illustrated by the transitive property in mathematics. The First Law Continue reading...

As an example of Physics in our daily life activities we can consider the interaction between our foot and the road when we walk. According to Newton`s third law for every action force there is an equal and opposite reaction force. (Harris, W., n.d.). Force is the pull or push needed to do a work. A force exists as a result of interaction, whenever there is an interaction between the two objects there is a force acting upon each object. When one object exerts a force on the second object, the second object also exerts an equal and Continue reading...
