  • Semiconductive Properties Of Metal Oxides

    data reveal a semiconductor behavior where the resistivity decreases with the increases of temperature. The decrease of the electrical resistivity with increase of temperature is resulted from the increase of the charge carriers that can overcome the energy barrier and participate in the electrical conduction where in metal complexes, the metal atoms act as charge carriers reservoir supply the complex with the free electrons and the metal ion can act as a bridge to facilitate the flow of…

  • Thermometric Error Analysis

    5. 3. 4 Typical application and thermometric error Consider a typical application such as the measurement of surface temperature by a surface mounted thermocouple as shown in Figure 5.9 (a). Figure 5. 9 : (a) Surface mounted thermocouple in Example 5. 1 (b) Thermal resistance network model Heat loss from the thermocouple is modeled as shown above by discussion leading to Equation 5.3. Thermocouple attached to the surface of a massive solid whose temperature we would like to measure.…

  • Brass Ball Experiment Essay

    end up fitting when it is heated or the ring might be too big for the ball after the ball is cooled. This might affect our results by thinking that the brass ball contrasted a lot after being cooled by the water when it was really just the thermal energy that made the ring…

  • Kinetic Energy And Potential Energy Essay

    Kinetic and potential energy play an essential role in the segments or phases in a heating or cooling graph representing an exothermic or endothermic process. Kinetic energy is the energy of a system that is in motion of the particles in the system. Potential energy is the energy of a system in which it represents the arrangement of the particles of the system. Kinetic energy and potential energy never increase or decrease at the same time, however, when one energy is changing the other remains…

  • Osmotic Respiration Lab Report

    Where M.R is the moisture loss ratio, M_0 is the initial moisture content, M_t is the moisture content at time t, M_e is the equilibrium moisture content, t is time (minutes), and a, b, c, and k are constants. For the effectiveness of diffusivity, Fick’s equation was used (5) to estimate the dehydration kinetic of different osmotic conditions. M.R=((M_t-M_e)/(M_0-M_e ))=〖8/π^2 e〗^((-(π^2 Dt)/(4L^2 )) ) …(5) Where D is the effective diffusivity, and L is the length of the (cubical) sample.…

  • Copper Calorimeter Experiment

    This experiment’s aim was to find the alcohol with the highest energy output when burnt using specific heat capacity of calorimeters. This data gathered only partially supported the hypotheses stated. There is an apparent trend between the heat energy of the alcohols and the amount of carbon atoms in the alcohols in the graphs shown. The first experiment (first graph) shows the results of the tests with a controlled calorimeter height of 20 centimeters. This means that the calorimeter, rather…

  • Personal Statement: A Career In Chemical Engineering

    about the engineering field and started to feel appealed by it. Between all specializations that the chemical engineering program has, I believe that the development of new types of energies and the development of polymers are the most interesting fields of the major. On the one hand, the rise of new types of energies is crucial when fossil fuels are no longer available,…

  • Thermal Niche Experiment

    Introduction: To fully understand the investigation, there are three main definitions to keep in mind. Thermal Niche is a development in which natural selection forms adaptation for an organism through temperature. Acclimation is the process for the organism to become accustomed to the climate change. Fitness is simply the survival of an organism, however, in the investigation, locomotion is more suited due to the focus on the affect temperature has on the organism’s performance. For this lab,…

  • Climate Change Lab Report

    When sea levels and temperatures rise as a result of climate change, how will plants react? In this experiment, the growth of Wisconsin Fast Plants (WFPs) will be tested when temperature and waterlogging are added to twelve WFP chambers. The question that will be attempted to answer is: How do factors of climate change—water and temperature stress—affect the growth of WFPs? Waterlogging is the act of adding too much water and temperature stress is extreme temperatures. This question is being…

  • The Effect Of Temperature On Living Organisms

    1. Temperature : A temperature is an objective measurement of hot or cold. It is measured by thermometer (Paul S. Welch,1938). Its most common unit is celcius. It is an important physical property of water because temperature controls the rate of most of the chemical reaction. As temperature affects the growth, reproduction and immunity of living organisms, therefore, drastic temperature changes can be fatal to living organisms. 2. pH : pH is a numeric scale used to specify the acidity or…
