For any sized rectangular sheet of card, investigate the size of the cut out square which makes an open box of the largest volume. Question 1 ---------- I began work on question 1, which was to investigate
the volume of amylase affects the rate of reaction between amylase and starch. Prediction: I predict that the greater the volume of amylase then the faster the rate of reaction between the starch and amylase will be. I predict this because of the lock and key hypothesis. The lock and key hypothesis explains how the substrate molecule (the starch) fits inside the enzyme. The substrate molecule is then broken up into many smaller pieces. In this experiment the larger the volume of amylase
Introduction: In this experiment we determined the difference in accuracy of two different sized cylinders. Accuracy is a measure of how close something is to its true value. To determine the accuracy we had to measure the volume and compare it to the theoretical volume, finding the relative error. Following this we used the density of water, 0.99720 g/mL, along with the mass we determined with a scale, to determine the volume of water in a 10 mL pipet using the formula D=mv. Objective: The purpose
the volume of the oil glass bottle you would need to find the volume of all three truncated cones and the volume of the half sphere and plus them all together. To find the volume of the truncated cones, you need to use the formula V = π [s (R + r) + R2 + r2], this will give you the volume for all the truncated cones. Also to find the volume of the half sphere is two-thirds times pi times radius3 (2/3 x π x r3). Once these volumes have been found and plus together, you would receive the volume of the
INTRODUCTION Some Types of measurements include length, volume, mass and temperature. Length is the measurement or extent of something from end to end. Volume is the amount of space that a substance or object occupies, or that is enclosed within a container. Mass, is the quantity of matter that a body contains, as measured by its acceleration under a given force or by the force exerted on it by a gravitational force. Temperature, is the degree or intensity of a het present in a substance or object
Measuring the Viscosity of a Liquid Aim The aim of this experiment is to find out how fluid Bath Oils really are by measuring its viscosity. Plan The first thing that I'll do is to measure the spheres volume by first measuring its radius. I will then, by calculating the spheres mass, be able to calculate the density of the sphere. This will be used later when calculating the viscosity of the bath oil. I will then find the density of the bath oil, also used during calculations later
Expansion and Contraction of Materials When most materials are heated they expand and this increase their volume. One example of expansion is the fitting of the starter ring gear to the flywheel. The gear is heated until it expands sufficiently to pass over the rim of the flywheel, and when it is cool the gear tries to return to its original size, this gripping the flywheel with considerable force. All metals do not expand equally when heated through the same range of temperature, e.g. aluminium
concentrations and volumes 5cm Hydrochloric acid (HCl) Water of different volumes Paper marked with a cross 2 Measuring cylinders Conical Flask Stopclock I will set the equipment up as shown in the diagram below Method I am going to measure out the right amount (50cm³) and concentrations of the sodium thiosulphate and hydrochloric acid. I will vary the concentration of the sodium thiosulphate but will still keep the volume of the acid the same. I will keep the volume (5cm³) and concentration
into three volumes, each taking place at a distinct time. Volume I highlights the correspondence in letters between Robert Walton, an Arctic seafarer, and his sister, Margaret Saville. Walton's letters to Margaret basically explain his expedition at sea and introduce Victor Frankenstein, the protagonist of the novel. Volume II is essentially Frankenstein's narrative, told in his point of view, with much action, death, and many more characters. There are a few chapters within this volume in which the
grad. cylinder., and a 25 ml pipette were determined by transferring each type to a tared 50 ml beaker. The density of copper was determined through volume displacement in water. The pipette was fond to be the most precise with a mean volume of 24.843±0.184ml. While the 25 ml cylinder had a volume of 24.601±0.708 ml and the 50 ml beaker had a volume of 24.074±1.98 ml. The density of copper was found to be 9.190±0.836, with an accuracy of 2.567%. The difference in density measurements could be due
written above Tintern Abbey', the concluding statement of the 1798 volume. The poem reads rather like the recitation of a liturgy. Wordsworth recollects his own faith by restating it, and in doing so he discovers its truth and its guarantee of continuity: "in this moment there is life and food / For future years" (ll. 65-6). However sceptical readers have become about the Wordsworthian-Coleridgean creed, the monumental quality of the volume is not entirely a figment of a literary history in search of Great
of how Changing the Volume of Water in a Container Affects Its Rate of Heat Loss Aim : To investigate how changing the volume of water in a container affects its rate of its heat loss. The variable of this investigation is the volume of water which is put in the container. What I already know: I already know that the larger the volume of water there is the less heat loss occurs. I can tell this from my previous pilot experiment where I investigated, if the volume of water in a beaker
perspective the object’s weight and that things which are really light usually float. We never think about how something that is big and heavy like a big ship can float. Although big ships are very heavy they can float because they have a very large volume and take up a lot of space. This particular experiment will mainly focus on whether an orange floats or sinks in water. My prediction was that the orange would float since it weighed less than the orange with the rind\peel on. This experiment will
become cloudy and make a cross below it to disappear. Method: Apparatus Hydrochloric Acid Sodium Thiosulphate Distilled Water 250cm ³ Beaker- I need a beaker big enough to see the cross and although the 100cm³ would be perfect volume wise I would prefer to use a bigger one so I can fit the cross under it and also be able to pour the reactants into it without any spillage 100cm ³ Measuring Cylinder- I have decided to use this cylinder for the Sodium Thiosulphate. I am only
50cm, which he uses to make drains. The semi-circle is the best shape for a drain. Prove this. I will prove this by comparing its volume to that of other shapes. On older houses there are semi-circular drains but on newer houses there is fancier ones like pentagon shapes. Is this because they are better or is it simply for design? To find the volume of a 3D object I have to find the area of a cross section and then multiply that by the length of the object. To make it easier IÂ’m going
Archimedes was one of the last ancient Greek mathematicians, following in the footsteps of Plato, Socrates, and Euclid. Historians call him "the wise one," "the master" and "the great geometer". Although he was also a scientist and inventor, it was his work in mathematics that has ranked him as one of the three most important mathematicians in history, along with Sir Isaac Newton and Carl Friedrich Gauss. Further, he was one of the first scientists to perform experiments to prove his theories. Archimedes’
relative atomic mass of Lithium by using two different types of methods The first method that was carried out was to determine the volume of Hydrogen produced. In this experiment a fixed amount of Lithium was used, in my case it was 0.11g. At the end of this experiment, the volume of Hydrogen gas I collected was 185cm³. Then using the solution of lithium hydroxide made from experiment one, I used it in the titrating experiment, to find out the total volume of Hydrochloric acid used to titrate
this is that the hulls you want for your boat will depend on what you will use the boat for. If you are ... ... middle of paper ... ...he x-axis. Finally you will analyze the graphs you made by telling about the relationship between buoyancy and volume of the different boat hulls. In the end, this experiment should have taught you how the different shapes of boat hulls effect how well your boat will be stable out on the water. The results from the experiment also have shown you that certain boat

What is the effect on volume when water and isopropyl alcohol are mixed together? Project Design Plan When two substances are added together, their mass is Conserved. This is according to the Law of Conservation of Mass. Does the same apply to volume? Mark W. Meszaros, PhD claims that when isopropyl alcohol and water are mixed, the mass of the two is added, yet the volume decreases (Meszaros, M W., PhD, n.d.). Problem Statement: When adding two substances together, one would hypothesize the addition
