Kinetic theory

determine the variations in boilingpoints of organic compounds. The boiling point of a liquid is the temperature at which its vapor pressure equals the external or atmospheric pressure. At this temperature, every molecules of the liquid acquire enough kinetic energy to overcome the intermolecular forces attracting them to the other molecules. Therefore, boiling points…

impulse = force X time. In collisions, momentum causes 'Inelastic Collisions ' and 'Elastic Collisions. ' Inelastic occurs when the total kinetic energy changes, but the momentum remains the same. During this type, the momentum is preserved, but the total kinetic energy isn 't, yet objects stick together after the collision. Elastic occurs when the kinetic energy and momentum remains the same and both objects would bounce away from each…

0.20 g of adsorbent was added to 20 mL of 50 mg/L dye solution and Vortex at 150 rpm for various time intervals at 5, 10, 15, 30, 60, minutes. The above steps were repeated using dye concentrations of 100, 150 and 200 mg/L dye solutions. Adsorbent dosage is an important parameter because it determines the capacity of adsorbent for a given initial concentration of dye molecules. Then their % absorbance’s were calculated by spectrophotometer (λmax=410) and thus amount adsorbed were calculated.…

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…

Diagram 1.6: Diagram showing tension force in the string (from 0 cm increasing in 1 cm until a displacement of 15 cm has been attained) This diagram shows the manner in which the tension force applied to the string was calculated. Starting at 0 centimeters, forces were provided in the string such that the string would extend one additional centimeter from the previous measurement. Using the Capstone® software, the force applied to the string was calculated at the given horizontal…

electron and the 1S hole heehehhegXVVUWEEEE++++++=12, (13) where Eg12 is the indirect energy gap of the hetero-NCs. The latter expression was used to calculate emission energies as a function of R and H. First three terms represent the band gap and kinetic energies of electron and hole, respectively, and the last four terms are components of total Coulomb correction: Veh = Weh + Ueh + Ve + Vh.

Kinetic energy comes from the relationship between the mass of the object in motion and its velocity. This energy has to be converted from another form of energy as the law of conservation of energy states that energy can not be created or destroyed only…

dam by making water fall from a certain height behind the dam to a power plant that is lower in height. As a result, the water behind the dam has gravitational potential energy, which is converted to kinetic energy as it falls to the power plant. The power plant uses its turbines to convert the kinetic energy to electrical energy. In this assignment, we are figuring out “to what extent can hydropower meet the electrical energy needs in the United States and China for the coming decades?”.…

1. What energy system(s) does the Wingate Test rely? Explain. The energy systems that the Wingate test relies on, is glycolysis and ATP-PCr. Anaerobic power is used for high intensity, short duration exercises, and activities. The Wingate test is anaerobic, which will utilize fuel through glycolysis and the ATP-PCr system. The Wingate test is very short in duration, and high in intensity, which means oxygen is not present in this process. The ATP-PCr system breaks down ATP into ADP for energy.…

gymnast. To begin, there is the running start; this is where energy plays a major role. During a gymnast’s running start for a vault, she gains kinetic energy, which is, simply put, the energy of motion. Looking at the equation for kinetic energy (KE = (½) mv^2), you can see that the more velocity produced during the gymnast’s initial run, the more kinetic energy she will have for the rest of the vault. Once the gymnast is at the top of her skill, for example, a handstand position at the top of…
