In this figure (10°C trial), the two test tubes are clearly labeled with 1 and 7, test tube 1 contains the 1 cm³ liver and test tube 7 contains the 5 mL of hydrogen peroxide. these two test tubes are in a 250 mL beaker containing approximately 125 mL of tap water and ice. The thermometer was placed in test tube 7, which contains the hydrogen peroxide to measure the temperature of the solutions. The hydrogen peroxide was poured into the test tube containing to the liver and was observed.…

Gay-Lussac’s Law states that when volume is held constant, temperature and pressure are directly proportional. Gay-Lussac’s constant (G) can be defined as P=GTwhere pressure is in atm and temperature is in Kelvin. All three laws play a role in the ideal gas law, PV= nRT where P stands for…

Thermal effect results from the change in the heat capacity of the gases in the combustion chamber. It is worth mentioning that EGR contains water and CO2 which have higher specific heat capacity than air. The change in absorbing heat is proportional to the added mass, to the heat capacity at constant pressure and to the difference in temperature between the EGR and the combustion temperature. ΔQ=Δm*Cp*(Tcom-Tegr) The change in specific heat capacity results from charge dilution and represents…

The main purpose of this experiment is to purify an impure solid by the technique of recrystallization. This technique involves several steps, selecting an ideal solvent, dissolving the compound in a minimum amount of boiling hot solvent, filtering insoluble impurities while the solution is hot; crystallizing the purified compound, and isolate the pure compound by vacuum filtration . The unknown used in the experiment was #4, which were white crystals. In order to determine the ideal solvent…

a) Heckel equation In 1961, Heckel proposed the most widely used equation describing pharmaceutical powder behavior in compaction. It was initially used to study the densification of ceramics and its correlation with pressure. It a first order process where powder pores elimination rate is correlated to the number of pores present. The rate of volume reduction increases as the number of pores decrease. Heckel equation relates the density, pressure and the pore fraction of the powder [16],.…

Coulter Counter Method. Schematic Diagram Diagram 1: The basic setup of coulter counter method. Test tube containing conducting fluid placed in the beaker containing same conducting fluid. Orifice in the test tube connect the circuit. Electrodes are placed in beaker and test tube and voltage is applied. Vacuum is applied in the test tube to allow fluid movement from beaker to test tube. Counting circuit will calculate the amount of particle and pulse height analyser will measure the particle…

3.3.2. Initial and Boundary Conditions. The pipe is subject to atmospheric pressure Po at time zero this represented initial condition . Boundary condition represented as at the pipe inlet profiles, uniform pressure Pinlet and its value change with concentration of nanofluid [φ%] and inlet temperature T0 = 60 ºC can be measured for all experimental . On the pipe wall, the pressure was atmospheric pressure Po . Moreover, flow and thermal fields are assumed symmetrical with respect to…

Evaporation: The rate of heat transfer in the evaporator is calculated using equations 10 and 11 Q_in=(εC)_evap (T_(in,evap)-T_evap ) (10) Where ε is the effectiveness of the evaporator, C is the capacitance rate for the air or chilled water passing through the evaporator. Tevap is the temperature of refrigerant in evaporator and Tin, evap is the temperature of the air or chilled water at the inlet of the evaporator. Equation 11 express Qin in terms of enthalpy. Q_in=m ̇_ref (h_4-h_1)…

This experiment will allow us to determine the molar mass of the unknown solute through calculating the difference in freezing point of the pure solvent and the solution with the unknown solute. This lab will show case one of the colligative properties of a solution. This property is dependent upon the number of solute molecules or ions and not the identity or chemical property of the solute. A common example is water which both freezes and melts at 0°C no matter the amount of water or the size…

The main objective of this lab was to collect 〖Co〗_2 gases that were given off by the Alka-Seltzer tablets and to identify experimental masses. The volume of gas was 724 liters, or 723.86 cm and the experimental mass was .0894 grams. A balance scale was used before and after the reaction to record the change in overall mass. First, using the scale, the flask, balloon, and Alka-Setlzer tablets were measured, 259.4 ±.05 Grams were found. What created the “〖Co〗_2 gases to be trapped” were the…
