Arlind Mara Paper Towel Lab Report AP Biology 15 September 2011 Which Towel is The Quicker-Picker Upper! To determine which of the most popular paper towel brands such as Bounty and Marcal would be the Quicker-Picker-Upper I conducted the following experiment during which I dipped 6in X 6in squares of paper towels into 100mL and measured the amount of water absorbed by the towels in 20 seconds. After averaging all 3 trials for the paper towel brands that I tested I arrived to the conclusion

The Ideal Gas Law Lab taught me that hydrogen is lighter than air‚ and can be ignited. The materials used for the experiment include 0.05 grams of magnesium‚ 1M H2SO4‚ water‚ a 100mL graduated cylinder‚ and a beaker. The hydrogen can be ignited with a match. First‚ the beaker is filled with water. The acid is then added to the graduated cylinder‚ with about ¾ inch left at the top‚ which is space for water. Afterward‚ the magnesium is added to the graduated cylinder‚ and it is inverted upside down

Lab: Gas Laws Purpose: Obtain a reference of temperatures effect on gas using Charles’ law when heating a capillary tube in water on a heated hot plate. Then‚ cooling the same capillary tube with ice while measuring the temperatures cooling effect on the gas bubble inside the capillary tube. Measurements of temperature change are taken with microLAB sensor and graphed using microLAB software. A final determination of experiments determined absolute zero versus actual absolute zero will be

A Case of Colorado Beer – Convenience Store Advocate One may state that upon the passing of the new beer law‚ some sales in the existing liquor stores may decline. Despite this possibility‚ this can present a major expanding opportunity for all the craft beer creators in the area. As a convenience store advocate‚ I support the passage of House Bill 1192‚ which would allow grocery and convenience stores to sell full strength beer. While there are arguments on both sides for and against this Bill

The purpose of this lab that was completed was to observe standing wave patterns in clamped strings‚ and understand the effect of the standing wave frequencies of changing the length (L)‚ tension (T)‚ and linear density (p) of the strings. Standing wave patterns in strings are observed at certain excitation frequencies for special values of L‚ T‚ and p. A standing wave can be defined as a vibration of a system in which some particular points remain fixed while others between them vibrate with the

Introduction: The goal of this experiment was to measure the amount of gas produced in various reactions. The Ideal Gas Law was needed in order to calculate the mass of reactants and moles of gas produced: ‚ where is the pressure in atm‚ is the volume in Liters‚ is the number of moles‚ is the ideal gas constant [0.082 (Latm)/(Kmol)]‚ and is the temperature in Kelvins. Considering the units on R‚ it was important to convert pressure‚ volume‚ and temperature to atm‚ L‚ and K‚ respectively. In

Experiment 4A: Determination of a Partition Coefficient for Benzoic Acid in Methylene Chloride and Water Experiment 4B: Solvent Extraction I: Acid-Base Extraction Using the System Benzoic Acid‚ Methylene Chloride‚ and Sodium Bicarbonate Solution Objective A: To accustom participants (students) to general procedures that are used to obtain a partition coefficient at the microscale level. We will gain experience in such practices as the transfer of microliter volumes of solutions with a Pasteur filter

the future strategy for both products which Cobra Beer and Kingfisher Beer. The aim of this report is to compare both of the products in the UK market and to get the future forecast that where both of the products have place in the market. The reason I have chosen those products is just because I am working for Cobra Beer head office and I wasn’t difficult for me to get the information for the company’s product I am working for. As far Kingfisher Beer is concern‚ I have really put my efforts searching

Coulomb’s Law 1. Objective - To study the validity of Coulomb’s law on a simple electroscope. This will be split into two parts; first measuring the the force as a function of distance‚ and second we will look at how the magnitude and sign of the charges affect the force. 2. Theory- As is well known‚ like charges repel and opposite charges attract. That being said‚ the strength of those forces also depends on the distance between the two charges
