Calorimetry Lab Report Waris Butt PHY 112 Mr. Fasciano Class #18336 06/08/14 Purpose: Heat flow will occur between objects in contact until no more heat flow is detectable. Using calorimetry to analyze heat flow quantitatively and the equation: Q = mc ΔT‚ to determine the specific heat capacity of an object and heat flow from or to an object; respectively. Materials: Circle K 44 oz Styrofoam cup with lid Large Plastic

technique is: Number Moles Concentrated Solution = Number Moles Dilute Solution. An instrument called a spectrophotometer detects the amount of light that passes through the sample and the percent transmittance can be recorded from the meter. In the lab‚ multiple homogeneous solutions are made. There was not a way to determine the differences in concentrations‚ but the Spec 20 made it possible to measure the difference. The Beer-Lambert Law is a graph used to record

Rachel Bohnenberger Professor Van Doorn ENVS 150-002 27 April 2015 GMOs Lab Report Introduction As the population of Earth increases exponentially‚ so does the demand for more food. One of the solutions to the question of how more food can be produced is Genetically Modified Organisms‚ or GMOs. There is an ongoing debate about whether or not GMOs are more beneficial or harmful to society. Some of the benefits to GMOs are: growing plants‚ such as corn‚ that are resistant to weeds and pests‚ larger

This prebiotically plausible proto-nucleic acid monomer (Figure 1)‚ is the amide formed between a cyanuric acid-functionalized hydroxy acid called 2-OH-CyCo4 (abbreviated as ψ) and the amino acid L-aspartic acid (abbreviated as D). Despite no obvious prebiotic route to this compound‚ it features certain principles that still apply to prebiotically plausible compounds. More specifically‚ when simple compounds containing hydroxyl and carboxylic acid moieties are dissolved in water and dried at elevated

Osmosis Lab Report Hypothesis: Osmosis will occur when there is an uneven distribution of solute in a solvent. The higher the solute in solvent‚ then there will be a higher rate of osmosis through the diffusion gradient forming a hypertonic or hypotonic solution. Solvent with equal or no solute forms an isotonic solution. Materials: Distilled water‚ sucrose‚ dialysis tubing‚ string‚ 250 ml beaker. Procedure: To demonstrate and isotonic solution we needed 3 inches of dialysis tubing. We

Corte Madera Scientific Report Abstract I examine how rising or falling tide can affect the water level of Corte Madera Salt Marsh in this report. The data is from Wednesday (June 19th) and Thursday (June 20th). My hypothesis is that tide and water level have positive relationship. From the result‚ I learn that the water level and tide have positive relationship. However‚ when tide changes its direction‚ the water level is likely to stay or little change. Introduction On June 19th‚ my
