Abstract The purpose of this experiment was to identify whether density is an extensive or intensive physical property. By using water displacement‚ the volumes of the paper clip samples were measured and the masses were obtained by using an electronic balance. Each mass and volume was unique to their sample so by using their values‚ density was used to identify substances in the lab. After conducting the experiment‚ the results showed that there was a positive slope between the different paper

The Experiment Gloria Isham Central Texas College Twenty- six men are chosen to participate in the roles of guards and prisoners in a psychological study led by a Doctor Archaleta for which each participant is to receive $14‚000 after two weeks. Travis has just lost his part time job and is a peace protester who wants to travel to India with his girlfriend. Barris is a 42-year-old who lives alone with a domineering mother‚ who has made him join the experiment to raise money for her hip operation

Relative Reactivity of Alkyl Halides Introduction Nucleophilic substitution of alkyl halides can proceed by two different mechanisms – the SN2 and the SN1. The purpose of the experiment was to identify the effects that the alkyl group and the halide-leaving group have on the rates of SN1 reactions‚ and the effect that the solvent has on the rates of SN1 and SN2 reactions. The SN1 mechanism is a two-step nucleophilic substitution‚ or unimolecular displacement. In the first step of the mechanism

Measurement of the Densities of Water and Alcohol Phuc Truong and Shane Steele Data Collected: September 8‚ 2014 2:05 P.M. Purpose: The purpose of the experiment is to measure the densities of liquids. Specifically‚ the two liquids that were used and measured in the research were deionized water (H2O) and alcohol (C2H5OH). Methods: Density is an intensive quantity that cannot be visually identified. Therefore‚ the most straightforward approach to this problem was to record the measurements of mass

The Relatives Came is the story of a family living in Virginia who visits their relatives in another state. This book appeals to an extensive range of children because its plot focuses on a large family living together throughout the summer and having to share a small space. Nevertheless‚ the initial discomfort later turns into a memorable experience as family members come closer together. The language style used in the book is age-appropriate and the characters are realistic without being over-exaggerated

Name Date Lab: Denisty – Solids and Liquids Part 1: Density Background Information: The density of an object is how much “stuff”‚ or molecules‚ a substance is made of. Density is how tightly packed the molecules are. To calculate the density of a substance we need to know the mass (weight) of the substance and the volume (how much space) of the substance. Mass is determined by weighing an object. Volume of regular shaped objects is calculated by measuring

DENSITY OF LIQUIDS AND SOLIDS by Lab instructor: Due date: Results and discussion: The purpose of the experiment was to determine the densities of the unknown liquid and solid as precisely and accurately as possible in order to identify them. It was carried out first on distilled water in order to rule out systematic errors. A 10 mL beaker was placed on a top pan balance and “tared”. The beaker was then removed and 10 mL of distilled water was pipetted into it before it was placed
