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

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

pneumatic trough‚ thermometer‚ screw clamp. DISCUSSION The quantitative relationship between the volume and the absolute temperature of a gas is summartzed in Charles’law. This law states: at constant pressure‚ the volume of a particular sample of gas is directly proportional to the absolute temperature. Charles’ law may be expressed mathematically: V ". T (constant pressure) V = kT o‚ : T = k (constant pressure) (1) (2) where V is volume‚ T is Kelvin temperature‚ and k is a proportionality constant

Name: _____________________________________ Block: _________ Date: _______________ Lab #14: Boyle’s Law Objective: To determine the relationship between the pressure and volume of a gas at constant temperature. Introduction: The relationship of pressure to volume for a gas in a rigid container was first described in 1662 by the Irishborn scientist Sir Robert Boyle (16271691)‚ and is known as Boyle’s Law. As long as the temperature of the gas remains constant‚ the pressure

Aim: To determine a value for the spring’s force constant‚ k. Introduction: Hooke’s Law indicates the relationship between the amount of extension‚ e‚ of a spring to the size of the force‚ F‚ acing on it. This relationship may be written as :- F = ke F = ke where k is a constant for which particular spring you are using. It is the force constant of the spring. * The force applying on the spring‚ F‚ is denoted by Newton in SI Units. (N) * The amount of extension of the spring

Title : The Beer-Lambert Law and Its Limitation Objective : 1. To determine the linear relationship between absorbance and concentration of an absorbing species. 2. To study the effects of molecular dissociation complex formation on the applicability of the Beer-Lambert Law. 3. To investigate the derivation and limitation of Beer-Lambert Law. Introduction: In optics‚ the Beer–Lambert law‚ also known as Beer ’s law‚ the Lambert–Beer law‚ or the Beer–Lambert–Bouguer law relates the absorption

Determination of a Rate Law Megan Gilleland 10.11.2012 Dr. Charles J. Horn Abstract: This two part experiment is designed to determine the rate law of the following reaction‚ 2I-(aq) + H2O2(aq) + 2H+I2(aq) + 2H2O(L)‚ and to then determine if a change in temperature has an effect on that rate of this reaction. It was found that the reaction rate=k[I-]^1[H2O2+]^1‚ and the experimental activation energy is 60.62 KJ/mol. Introduction The rate of a chemical reaction often

The purpose of this lab was to learn about Newton’s laws of motion by completing an experiment‚ to see how the forces act on objects. The independent variable of this experiment is the type and amount of materials used for the interior of the vehicle (out of the material list) and how they were used. The dependent variable is how and if the interior of the vehicle protected the egg from getting cracked. The controlled variables of this experiment were the height that the vehicle was dropped from

Ideal Gas Law Lab 1. Procedure: First‚ we used a balance to weigh the canister of gas‚ and recorded that mass as the original weight. Then‚ we filled a large bucket with water and recorded the temperature. We then filled a small test tube with water at the same temperature and poured that water into a graduated cylinder to measure the original volume of water in the tube. We then poured the water back into the test tube and placed the tube into the bucket with the opening upwards‚ turning the
