    Chapter 2 ENERGY CONVERSION AND GENERAL ENERGY ANALYSIS W hether we realize it or not, energy is an important part of most aspects of daily life. The quality of life, and even its sustenance, depends on the availability of energy. Therefore, it is important to have a good understanding of the sources of energy, the conversion of energy from one form to another, and the ramifications of these conversions. Energy exists in numerous forms such as thermal, mechanical, electric, chemical

    Ghhhhhhhhhhhhhhhhhj, In the beginning it was dark and cold. There was no sun, no light, no earth, no solar system. There was nothing, just the empty void of space. Then slowly, about 4.5 billion years ago, a swirling nebula, - a huge cloud of gas and dust was formed. Eventually this cloud contracted and grew into a central molten mass that became our sun. At first the sun was a molten glow. As the core pressure increased, and the temperature rose to millions of degrees - a star was born. Through

    The Formation of a Star

    The basic idea of star formation is gravitational collapse – the contraction of a region of gas under the influence of gravity. This is a simple process that would be expected to occur in any region of material dense enough for collisions between atoms to radiate away energy. However, the gas must be dense enough for collisions to occur and the temperature must be low enough for the atomic velocities not to be able to escape the system's gravity, so star formation only occurs in a few areas.

    Nano Technology

    techniques and tools being developed today to make complete, high performance products. | With 15,342 atoms, this parallel-shaft speed reducer gear is one of the largest nanomechanical devices ever modeled in atomic detail. LINK | The Meaning of Nanotechnology When K. Eric Drexler (right) popularized the word 'nanotechnology' in the 1980's, he was talking about building machines on the scale of molecules, a few nanometers wide—motors, robot arms, and even whole computers, far smaller than a cell. Drexler

    understanding of thermodynamic properties of solid. By using the average sound velocity according to the methods in Ref. [47], the calculated density of molecule, transverse, longitudinal, sound velocity and Debye temperature are given in Table 5. The results have predicted that the Debye temperature (TDebye) was decrease with increasing the atomic number of the element (Mn, Tc, Re) in the sequence Mg3ReH7 < Mg3TcH7 < Mg3TcH7 <

    System Theory

    collection of elements or parts (say, the organs or cells), systems theory focuses on the relations and interactions between the parts, which connect them into a whole (see holism*). The particular arrangement of elements and relations determines an emergent* organization, or system*. That organization is abstract, independent of the concrete substance of the elements, which may be atoms, molecules, cells, transistors

    Biochem

    the interaction of a biological molecule with water is very important. That interaction is influenced by two primary causes: size and polarity (charge). The smaller a molecule is, the more likely it is to be willing to associate with water (dissolve). Also, the more polar and/or charged a molecule is, the more likely it is to be willing to associate with water. Since biological molecules are often very large, it is common for the different parts of the molecule to interact differently in water

    Vinegar as Alternative Battery

    CHAPTER I: INTRODUCTION a. BACKGROUND OF THE STUDY Vinegars had been used at home solely for cooking. Most people are not aware that it actually has other uses at home like lighting small LED bulbs. Thus, when the researchers came across this project on the internet, we grabbed the opportunity of proving whether or not this is a possibility. With the cheap and readily-available materials, this project can provide households with an alternative source of light that can easily be done and
