Volume Three

Fermentation is the anaerobic process by which glucose, or other sugars are catabolized by microorganisms without an electron transport chain, like yeast (Campbell, 2004). In experiment one the yeast and glucose acted as reactants, with the yeast breaking down the glucose, producing the products CO2 and ethanol. The overall reaction for the alcoholic fermentation that took place can be represented as 2 pyruvate + 2NADH-> 2NAD+ +2CO2 + 2 ethanol (Campbell, 2004). This biological process allows cells

Careful emptying of the plastic bottle was ensured to preserve accurate volume measurements in the subsequent trials. The mass of the empty, capped plastic bottle was determined using the analytical balance. Afterwards, 25.00 mL of Light Coke® solution was measured in the burette by filling it completely (50.00 mL), then draining

equal volumes of both soft drinks. Consequently, if the volume increased by a doubled amount under similar experimental conditions where temperature and pressure remained constant, the density of the soda would not be expected to change due to density being an intensive property that is a ratio between the mass over the volume of a substance.2 As an intensive property, density, under similar experimental conditions, will be the same without regards to the amount presented. Doubling the volume would

particles, and reaching thermal equilibrium faster. This is what happens when a hotter body is subjected to a colder one. Research Question: How does the surface area to volume ratio

Purpose: To find the relationship between the mass and the volume of the four samples. Relationship between Mass and Volume Longest (1) Medium (2) Short (3) Shortest (4) Mass (grams) 15.197g 11.900g 8.708g 5.496g Pre Water Displacement (milliliters) 65 ml 65 ml 65 ml 65 ml Post Water Displacement (milliliters) 78 ml 75 ml 73 ml 71 ml Volume (milliliters) 13 ml 10 ml 8 ml 6 ml Post Lab Questions: The slope, found by the rise over run of 4.5 over 4, tells the average density for the samples.

The Relationship Between Density and Sugar Content Danielle Shaub Partners: Emily Alexander, Bill Dempsey, Shayla Ho Lab Performed 03/11/15 & Lab Report 04/07/15 Abstract: Using solutions of sugar and water alongside cola, density and percent sugar can be related. The purpose of this lab is to discover how and with what benefit these factors can be related. Using assorted measurements and the standard curve of the calculated densities and percentages of sugar solutions, it was learned that cola

AIM OF THE EXPLORATION ÿ Explore Integral Calculus usage to find the Volume of the solids ÿ Identify the cross-section of the solid ÿ Suggest an Algorithm for finding an expression for the Volume INTRODUCTION We learnt in the Applications of the Integral calculus to find the area under the curve. This can be divided in following three cases: ÿ Area below any given curve and above the X-axis ÿ Area between the two given curves If definite integration can be used to calculate the area of

objective of this lab was to determine the relationship (if any), between the pressure and volume of a gas given the temperature and # of molecules remained constant. Using the Boyle's law apparatus, and textbooks to demonstrate pressure it was concluded that there was a relationship between pressure and volume. However, the relationship was not a direct relationship, and it was determined that the pressure and volume of a gas are inversely proportioned. Thus,proving Boyle's theory correct. Introduction

made by a company manufacturing them will be assessed. This will be done by taking different volumes of water using a 10 mL graduated pipet, a 50 mL graduated buret, a 10 mL graduated cylinder, and a 50 mL graduated cylinder. After weighing each volume, we used the density of water at our room temperature to calculate the volume of each water samples. Then we compared that calculated volume (actual volume) to the one initially took; we used that result to assess the accuracy of our glassware by doing
