Recommended: Law of thermodynamics

Introduction
Thermodynamics is the study that shows the relevance between the work and the heat. Thermodynamics has 2 laws. The first law declares that the heat and the work are mutually interchangeable. The second law states that a entropy of a secluded regulation can never decrease, because the secluded regulation always develops toward the equilibrium thermodynamic. These two laws attitudinize the process of a heat engine.The first law is the implementation of the preservation of energy to the regulation. The second law defines the potential eligibility of the machine and guidance of the energy flow.
A heat engine is a method that executes the transformation of thermal energy or the heat to mechanical energy. That mechanical energy can be used as a mechanical work. This work can be manifest by bringing a working material from a high heat condition to a lower heat condition, by that the heat engine will produce calorific power that creates higher temperature conditions of the working substance. After generating a higher temperature state to the working substance a work will be p...

  • Analysis: Joe Science Vs. The Water Heater

    868 Words  | 2 Pages

    Thermodynamics is essentially how heat energy transfers from one substance to another. In “Joe Science vs. the Water Heater,” the temperature of water in a water heater must be found without measuring the water directly from the water heater. This problem was translated to the lab by providing heated water, fish bowl thermometers, styrofoam cups, and all other instruments found in the lab. The thermometer only reaches 45 degrees celsius; therefore, thermodynamic equations need to be applied in order to find the original temperature of the hot water. We also had access to deionized water that was approximately room temperature.

    Another way to control the heat is to decrease the distance between the boiling tube. and the container of the. The amount of energy released increases with the number of bonds. present in the chemical substance or fuel. That is because each bond has a certain amount of energy stored in it therefore the more bonds the more energy is stored and more energy is released if these bonds break through the combustion process.

  • The Future of Internal Combustion

    711 Words  | 2 Pages

    For over a century people have relied on automobiles, planes and trains as means of transportation, industry and agriculture, it has become such a successful necessity in the modern world that it has become a need for people to use them to get by. Now sure the three basic means of transportation are entirely different in the way the function and their use. All of these means of transportation would not be possible without this invention transportation could not be possible, The Internal Combustion Engine. You might be wondering what is exactly is an Internal Combustion Engine? It’s actually a simple concept but the way it’s performed can becoming very complex. The function of is to create a pulling force through a controlled explosion of compressed air and fuel inside a combustion chamber which then pulls a crank. Depending on what type of platform the engine is on will determine what the crank turns, for an example in a car the crank then turns either a front or rear axle which that axle transversely turns a wheel. In order for this engine to function in needs three elements - air, fuel and spark and without one of these elements the engine will not function, so it takes precise timing and careful planning by the Engineers to make the engine work as required.

    A four stroke engine is the kind most commonly found in automobiles, and operates in four distinct steps or “strokes”; induction, compression, combustion and exhaust. On the first stroke, the piston moves downward and causes a pressure in the cylinder which is less than the atmospheric pressure outside of the engine. As a result, the air outside of the engine moves into the cylinder where there is less pressure, and is actually forced in because of the now higher pressure outside of the piston. On the second stroke, the piston moves upward and compresses the air with gasoline. The sparkplug ignites the mixture which combusts and moves the piston downward for the third stroke. This is where the power of the engine comes from. The piston then returns upward for the fourth stroke in order to push out the exhaust gases. Because the power of an engine is dependent upon the volume of air that can be drawn into the cylinders, it becomes limited at a certain point when the cylinder reaches its maximum negative pressure, and no more air can be sucked in. Not even an efficient engine, which at best is said to be on...

  • Essay On Dynamic Systems Theory

    617 Words  | 2 Pages

    The dynamic systems view was developed by Arnold Gesell in 1934 and explores how humans develop their motor skills. From Mr. Gesell’s observations, he was able to conclude that children develop their motor skills in a specific order and time frame. He concluded that children roll, walk, sit, and stand as a result of several factors – the ability to move, the environmental support to move and the motivation/goal to move. Once the child has the motivation, ability, and support, they accept the new challenge. After several failed and successful attempts, they begin to fine-tune and master the movement with continued support and motivation. The dynamic systems theory is not a random process that children experience, the skills are calculated and develop over a period of time.

    Heat energy is transferred through three ways- conduction, convection and radiation. All three are able to transfer heat from one place to another based off of different principles however, are all three are connected by the physics of heat. Let’s start with heat- what exactly is heat? We can understand heat by knowing that “heat is a thermal energy that flows from the warmer areas to the cooler areas, and the thermal energy is the total of all kinetic energies within a given system.” (Soffar, 2015) Now, we can explore the means to which heat is transferred and how each of them occurs. Heat is transferred through conduction at the molecular level and in simple terms, the transfers occurs through physical contact. In conduction, “the substance

  • How a Gas Turbine Engine Works

    1201 Words  | 3 Pages

    The invention of internal combustion engines in the early 19th century has led to the discovery of utilisation of cheap energy that is petroleum and this enabled the world to develop and progress into the modern world today. Humans were able to accomplish more work done with little manual labour, using internal combustion engines powered by fossil fuels. Internal combustion engine are mechanical power devices that convert heat energy to mechanical energy with the combustion process taking place in a system boundary (Rolle, 2005). Among the internal combustion engine invented in the 19th century were the Otto engine, Diesel engine and gas turbine engine. Gas turbine engine is one of the popular engines used today due to its high torque per weight ratio relative to other types of internal combustion engines. As explained by Cengel and Boles (2011), the gas turbine engine works on a 6 stages process, namely air intake, compression, fuel injection, combustion, expansion and exhaust (refer to Figure 1 in Appendix 1).

    Exergy is a term use in thermodynamic where also some terms found in the literature that are equivalent to: available energy, essergy, utilizable energy, available energy and availability. The exergy of the system is defined as the maximum useful work that can be done by the composite of the system and a specified in reference environment. The reference environment is assumed to be infinite, in equilibrium, and to enclose all other systems. Typically, the environment is specified by stating its temperature, pressure and chemical composition. Exergy is not simply a thermodynamic property, but rather is a property of both a system and the reference environment (Holman, 2009). Exergy can be destroyed by irreversibility of a process.

  • Thermodynamics

    Thermodynamics is the branch of science concerned with the nature of heat and its conversion to any form of energy. In thermodynamics, both the thermodynamic system and its environment are considered. A thermodynamic system, in general, is defined by its volume, pressure, temperature, and chemical make-up. In general, the environment will contain heat sources with unlimited heat capacity, allowing it to give and receive heat without changing its temperature. Whenever the conditions change, the thermodynamic system will respond by changing its state; the temperature, volume, pressure, or chemical make-up will adjust accordingly in order to reach its original state of equilibrium.

    Classical physics is basics of all physics that says matter and energy are two distinct concepts according to newton’s law and theory of electromagnetic radiation. Classical physics is centred on these assumptions, position and momentum of particles can be calculated at any instant when it travels in a trajectory, the energy of a particle may adopt any arbitrary value and waves and particles are separate concepts. However classical physics failed to explain those assumptions on atomic scale because those assumptions made on macro scale which caused some big problems by end of 19th century. Nevertheless problems in classical physics resolvable by modern mechanics which known as quantum mechanics. [1, 2]
