    7.59 From the stress–strain data for poly(methyl methacrylate) shown in Figure 7.24, determine the modulus of elasticity and tensile strength at room temperature [20°C (68°F)], and compare these values with those given in Tables 7.1 and 7.2. Solution From Figure 7.24, the elastic modulus is the slope in the elastic linear region of the 20C curve, which is The value range cited in Table 7.1 is 2.24 to 3.24 GPa (325,000 to 470,000 psi). Thus, the plotted value is a little on the…

    There are small particles in the air called aerosols. They are found in fog and smoke. These particles become larger in size if two processes occur. The first process is water vapor accumulating onto a particle. The next process is cool, rising air supporting the particle. Once the aerosol particles are large enough, they become cloud droplets that will have a different mechanism of growing. Cloud droplets grow differently because they are larger in size. Instead, they grow by a new process…

    Gummy Bear Experiment

    For our diffusion experiment our group decided to work with salt water and gummy bears. Our experiment tested the weight of the gummy bears per salt dilutions. Our tests included 1g 2.5g 5g, 1.5g, and 10g of salt diluted with water. We knew that the higher the concentration of salt diluted into the water the heavier the diffused gummy bear would be, therefore we measure weight as our numerical data. My hypothesis was that the 10g dilution of salt would have the gummy bear with the largest…

    The Kinetic Molecular Theory explains why gases behave the way they do. It explains how gas particles are in constant motion and create collisions that results in pressure. The theory is split up into four different postulates. Number one explains how gases are made up of tiny particles. To prove that those particles take up space, postulate #2 tells us that the particles collide with each other and those collisions make pressure. Pressure can either expand or shrink a flexible container,…

    The synthesis of Aa-g-poly(MAA) involve the optimization of various reaction conditions like initiator concentration, monomer concentration, crosslinker concentration, solvent concentration and pH. After the optimization of various reaction parameters the replications were carried-out in triplicates for the reproducibility of the results and statistical of the results obtained. It was performed using the Statistical Package for Social Science (SPSS) version 10. Statistical results of the…

    composite has been investigated. For that purpose, the PMMA samples with Al2O3 additive prepared with different percentages(0,15,25,35 and 45) wt.% and different thickness. The experimental results showed that the D.C electrical conductivity increased with increasing the alumina concentrations and temperature. Also the activation energy change with increasing of additional alumina. The dielectric constant, dielectric loss, A.C electrical conductivity are changed with change the concentration of…

    of the trials treated with 1.0mL fertilizer will be higher than those treated with 0.5mL or 0.0mL. Although wastewaters contain elements which are vital for the Spirulina growth, as it contain other unknown substances as well, its influence on the rate of growth of the Spirulina's cannot be unambiguously hypothesized. Since bicarbonate and sodium carbonate were not added to the effluent water but only to the portable water, it is assumed that the higher concentration of the…

    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…

    Phase Solubility results The phase-solubility diagram (figure 1) obtained was classified as AL type(20) because the apparent solubility of ISH increased linearly with β-CD concentration over the entire concentration range studies, thereby suggesting the formation of a water soluble complex. A slope value of less than one indicated that an inclusion complex in a molar stoichiometric ratio of 1:1 was formed between the drug and β-CD in solution. The stability constant (718.58 M–1), computed from…

    supported as the rate of reaction did increase as the concentration and the temperature increased. The concentration, or molarity, of the reactants increased in relation to time in the form M=1.1541e0.0016t. This is an accurate relationship as the volume remains the same as the number of molecules increase, thus the rate would increase exponentially as the molecules collide at a constant growth rate. This is also a reliable model as the R² value is 0.9697. The hypothesis that the reaction would…
