    The purpose of this experiment was to determine the thermodynamic properties of the entropy, enthalpy and free energy, as well as the solubility product of borax as a function of temperature from the dissolution of borax in an aqueous solution. Thermodynamics is the study of heat and its transformations. The properties of thermodynamics are entropy, enthalpy and free energy. The properties of thermodynamics can be viewed in terms of spontaneity. Spontaneity is a spontaneous change of a system that occurs by itself under specific conditions, without input of energy from the surroundings. Entropy, ΔS˚, is the tendency for the universe to move towards more disorder. If the value for entropy was negative, then the amount of disorder within a system…

    Thermodynamics Thermodynamics is the study of heart and its transformation into mechanical energy. It bypasses the molecular details of systems and focuses on the macroscopic levels of mechanical work, pressure, temperature, and their roles in energy transformation. Coined by the British physicist Lord Kelvin, the scale of thermodynamics is measured in units of "K". Zero K, or -273˚ C, would represent absolute zero. Absolute zero is the temperature at which no more energy can be extracted from…

    The Laws of Thermodynamics dictate that the universe is constantly becoming more disordered. If this is truly the case, then how have life forms as ordered as the ones here on earth possibly come to exist? The universe’s relentless drift toward pure chaos poses quite a challenge to the order that is life, but by using concepts of thermodynamics and biophysics, life forms continue to subsist. Life itself is in a perpetual struggle with the Laws of Thermodynamics that both are the foundation for…

    Chemical thermodynamics is the study of the interrelation of heat and work with chemical reactions or with physical changes of state within the confines of the laws of thermodynamics. It involves not only laboratory measurements of various thermodynamic properties, but also the application of mathematical methods to the study of chemical questions and the spontaneity of processes. The structure of chemical thermodynamics is based on the first two laws of thermodynamics. Starting from the first…

    balance within their lives in order to demonstrate an equilibrium and security. In contrast, by expressing the laws of thermodynamics, it is stressed that through the process of discovering a balance, obstacles can be achieved. Thermodynamics highlights the stream of science attentive to heat and conversions to different forms of energy and work. Not only does the thermodynamic state define volume, temperate and pressure, it will contain heat sources giving a capacity, and change state. The idea…

    Q1) What are the three main scientific concepts regarding the Gas Turbine Engine 1. Entropy and the Laws of Thermodynamics  Definition: The first law of thermodynamics states that the total energy of the system is constant and that energy can neither be created nor destroyed and can only transform from one form to another. This means that we can't create noting from something, and we can't create something from nothing. Energy exists and cannot become nonexistent and nonexistent energy cannot…

    Introduction Thermodynamics is the study of heat and chemical transformations as a result of energy changes, energy is what keeps things moving in our everyday life and is applied to nearly everything to a point where knowledge of thermodynamics is common sense weather we know it or not. Now a days every household, car, office and even laptops and electronics have air conditioning which has allowed for appealing aspects of commercial use and consumer consumption, but what we don 't consider is…

    most difficult topics to understand in thermodynamics for many students. Students can learn and understand, difficult and abstract concepts better if they are able to see these concepts, in for example, with a simulation. So, in an attempt to better understand the concept entropy and reversibility along with irreversibility of a closed system, we conducted a simulation of an irreversible process of several types of mixing with different substances at different temperatures. This simulation will…

    Thermodynamics of Cheetos Purpose: to analyze the caloric content of snack foods, by determining the calories of heat given off by a Cheeto, or other snack foods, as it burns. Procedure: The food sample (Cheeto) was placed on a food holder, and the initial combined mass of the food holder and the Cheeto was measured and recorded. Using a graduated cylinder, 50-100 milliliters (ml) of water was measured and added to an empty soda can that was cut in half and cleaned. The soda can was…

    Trayc Poppenhager May 5, 2015 TA: GK Chem 341 Thermodynamics and Kinetic Control Goal: The overall goal of this experiment was to learn and observe about kinetic and thermodynamic control of different reactions by noticing which product forms faster or slower and possibly which reaction is more stable than the rest of the reactions. Significance: Organic chemists find using kinetic and thermodynamic control useful because they use the concept of the reactions to figure out…
