Lab 02: Lighter Than Air? A Density Study Date Performed: 09/08/2014 Date Submitted: 09/16/2014 Mariel Allegra Del Valle 1/6 Lab 02 - Lighter than Air? A Density Study: Lab 02: Lighter Than Air? A Density Study Del Valle‚ Mariel Allegra Abstract This experiment is composed of three parts. The purpose of the first experiment is to find the density of dry ice by using the method of displacement volume. Before the experiment‚ it was thought that the density would decrease over time

Value density/ packaging density IBMS 203 Huang Yang 0842317 Value density is defined as the value of a good per pound of weight. For example‚ the value of a pound of diamond which is much higher than the value of a pound of bananas. That is the value density‚ two goods have same size and same weight‚ but they have different values. It is used to determine a product where should be stored and how can it shipped. It can show how important of transportation cost in the total product

In Parts A and C‚ the relationship between surface area and volume was investigated. Plasticine was formed into a cube and a sphere; both shapes were cut in half. It was found that plasticine volume should not vary‚ two halves have a greater surface area than a whole‚ and cubes have a greater surface area than spheres of the same volume. In Part B‚ the relationship between diffusion and surface area to volume ratio was investigated. Three agar-phenolphthalein-sodium hydroxide cubes of different sizes

Restriction Fragment Length Polymorphism and Southern Blotting 1. Abstract The aim of the experiment was to be introduced to the techniques involved in the identification of restriction fragment length polymorphisms. Restrictions were carried out using three different restriction enzymes‚ ECORI‚ HindIII and BstELI with their buffers. Lambda (λ) DNA was then examined using electrophoresis and Southern blotting. The results showed that λ DNA was best digested by EcoRI as all of the expected bands

Purpose of lab 1.4 Measuring Volume by Displacement of Water was to determine the fraction of air in different granulated solids. The lab cocised of one test done on four different granular solid; with up to 3 trials on each solid. When all tests are done and put in tables‚ and the calculations are made‚ the conclusion is that grain size does not affect that fraction of air. To be able to find the fraction of air‚ 3 measurement had to be taken‚ the volume of the solid with air‚ the volume of water

Arc Length The definition of radian measure s = rθ The unit circle An angle of 1 radian Proof of the theorem IT IS CONVENTIONAL to let the letter s symbolize the length of an arc‚ which is called arc length. We say in geometry that an arc "subtends" an angle θ; literally‚ "stretches under." Now the circumference of a circle is an arc length. And the ratio of the circumference to the diameter is the basis of radian measure. That ratio is the definition of π. π | = | C D | . |
