This lab report will be detailing the steps taken and the results discovered when using spectrophotometry to determine the percentage of copper in a copper-clad penny and the thicknes of the copper layer on the copper-clad penny. After 1982‚ copper coating has been used in the creation of the penny because the cost of pure copper has increase to the point that the amount needed t omake a penny cost far more than the actual value of the penny. This lab allowed us to see just how much copper coating

Coulomb’s Law Purpose: The purpose of this lab was to demonstrate that the force between two stationary charges is directly proportional to the product of the charges and inversely to the square of the distance between them. Coulomb’s law tells us that the force between two charges depends (1) linearly on the strength of each charge‚ and (2) inversely on the square of the distance between them. Mathematically we would write this as . Procedures Part1 Begin by removing the right side

Chemistry Lab Report Water Hydration Introduction: A hydrated crystal or hydrated occurs when water becomes tightly attracted to a metal salt base on it’s polarity. The water molecules maintain integrity as molecules‚ however they are considered to be part of the formula of the hydrate. When the hydrate metal salt crystal is heated‚ the attractions to the water are broken by the heat energy and the water escape from the crystal. After heating the salt crystal is called as anhydrous‚ which

| | MUHAMMAD HAFIZ BIN ABDUL WAHAB | 121008711 | MARKS | INTRODUCTION The Reynolds number (Re) is a dimensionless number that gives a measure of the ratio of inertial forces to viscous forces and consequently quantifies the relative importance of these two types of forces for given flow conditions. Measurement of the fluid flow‚ often must understand its flow‚ flow rate distribution. Reynolds number is the characterization of fluid flow characteristics of an important parameter. Fluid flow

and Humidity Lab Name__ __________________ This activity will look at two of the most fundamental and important elements of weather: temperature and humidity. Objectives: 1. The students will discover the need for measuring instruments to quantify weather observations. 2. The students will learn how to use a sling psychrometer to determine temperature and relative humidity values. 3. The students will explain and understand the difference between absolute and relative humidity and

Somatosensation Lab Using Two Point Thresholds Alex Mendelson 2/24/2014 Two Point Thresholds This week in Sensation and Perception Lab we performed a lab that measured an individual’s somatosensation‚ which is their sense of touch. In order to measure the sense of touch we manipulated the thresholds of sensation by using the two point threshold procedure. The two point threshold procedure measures the smallest distance of two separate but adjacent points of stimulation on the
