  • Piere Bouger, August Beer, And Laser Reflection Methods

    The light extinction method was developed based on the works of Piere Bouger, August Beer, and Johann Heinrich Lambert (1760). Bouger observed for the first time that the light intensity of a candle decreases when it passes trough a transparent medium and appointed the length and the medium property as the main parameter to explain the light extinction. The correlation of absorbance and light path was proposed by Lambert. Finally, Beer concluded that absorbance is also proportional to the…

  • Catechol Oxidase Lab Report

    Introduction: Enzymes have a huge effect on the human body and other organisms. Enzymes are catalysts that are used to accelerate the reaction process by lowering the activation energy. For this experiment the catechol oxidase was extracted from potatoes. The enzyme is called catechol oxidase because the oxygen is reacting to catechol. Catechol oxidase causes the browning of the fruits and vegetables because the compound is toxic to the bacteria. The purpose of this experiment is to…

  • 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.…

  • Crayfish Behavior

    Crayfish are freshwater crustaceans that use their claws called chelipeds,for warning off predators. When frightened, these crayfish lift their chelipeds to make threatening gestures, all while moving backwards or staying still. We examined how long it would take for crayfish to calm down once removed from the water and if the temperature had any influence to this observation. To do this, we placed two crayfishes in room temperature water and another two in colder water for an interval of five…

  • Temperature And Temperature Experiment

    measure hot-water bath. Used beaker tongs to remove beaker from the hot plate between 50 and 60 degrees Celsius. Readings taken again. Used beaker tongs to place beaker back on hot plate and heated between 80 and 90 degrees Celsius. Flask placed into boiling-water bath and readings were taken. Removed flask and temperature probe and stopped data collection. Results: Pressure (kPa) Temperature (oC) Temperature (K) Constant, K (P/T or P*T) Ice-bath 92.63 1.8 274.95…

  • Pump Essay

    The water powered arm comprises of two chambers, one fitted into the other in a telescopic way. The width of the internal chamber is 14cm and its length is roughly 30cm. At the point when completely expanded the aggregate length of the two barrels is around 95.5cm. The prolongation and constriction of the internal barrel inside the external chamber gives the dish its development from east to west. The external surface of the inward…

  • Analysis Of Consider The Lobster By David Wallace

    but uncomfortable (Wallace 68). Wallace’s primary is claim is this; if animals feel the pain that we think they do when they are killed to be consumes, what makes that okay in our minds? Wallace highlights the moment when you put the lobster in the boiling water and you can hear their claws rattling and clanking as the lobster tries to push off (Wallace 69). Again, another effective use of the pathos…

  • Water Distillation Essay

    in that saline water is heated, producing water vapor that condensed to form freshwater. In an industrial plant or laboratory, water is heated to reach the boiling point to produce the maximum water vapor amount. To make it economically in a desalination plant, the applied water pressure being boiled is modified to control the boiling point due to the reduced atmospheric pressure on the water, the required temperature to boil water decreases when moving from sea level to a higher elevation.…
