Objective The objective of this lab is broken into two parts. The first is to recognize the principles of flame ionization and atomic spectra. The second is to observe and thus further understand the line spectra for multiple elements or molecules as well as determine the correlation between emission spectra and atomic structure. Experimental Procedure Procedure 1: Observation of Line Spectra by Discharge Tubes Six discharge lamps were selected – argon‚ carbon dioxide‚ helium‚ hydrogen‚ iodine

Calculations- 1. Main Show Tank Calculation: The main show tanks radius is 70 feet. Based on that the tank is a sphere-shaped and we have to find the volume‚ I used the formula for the sphere volume which is: V= 4/3(3.14 x r^3) V= 4/3(3.14 x 70^3) V= 4/3(1‚077‚020) V= 1‚436‚026.66666... V= 1‚436‚027 But I have to find the volume of the quarter sphere-shaped‚ so: V= 1/4 x 1‚436‚027 V= 359‚007 The volume of the quarter-shaped tank is 359‚007 cubic feet Holding Tank Calculations- 2.

Kara Vo Florence A1 10/25/17 Weighty Matter Lab 2.3 Problem: What is the relationship an object’s mass and an object’s weight? Design: In this lab‚ we are finding the relationship between an object’s mass and an object’s weight by creating a graph that represents the gravitational field strength. On the graph‚ the mass of the object (m) was located on the x-axis because it’s the independent variable. The weight of the object (Fg) is on the y-axis since it’s dependent on the mass of the object

Research on Conduction‚ Convention‚ and Radiation Conduction is the exchange of warmth between substances that are in direct contact with one another. The better the conductor‚ the all the more quickly warmth will be exchanged. Metal is a decent conduction of warmth. Conduction happens when a substance is warmed‚ particles will acquire vitality‚ and vibrate more. These atoms then chance upon adjacent particles and exchange some of their vitality to them. This then proceeds with and passes the vitality

I have chosen to use Donald Schon’s (1983) model of reflective practice to reflect on my experience of leading the change in the school environment. I feel this was the most suitable model as it allowed me to reflect-on-action how I executed the task (Schon‚ 1983). I have been implementing a change in the primary school where I work. As a teaching assistant I feel confident in suggesting changes we could put in place‚ however‚ this project enabled me to enhance my development and initiate a change

Introduction The natural source of both plasma and electromagnetic radiation (EMR) is the sun. There are various similarities such as the presence of electric and magnetic field in both EMR and plasma. Both transport contain energy and are ubiquitous in the universe. However‚ there are large differences between EMR and plasma. Differences between EMR and plasma EMR is energy that propagates through a medium in the form of EM waves. It has an electric and magnetic field which oscillate in

In physics‚ the charge of a volume is commonly described by a quantity called the charge density or the charge distribution. When the electric field that arises from the charge distribution exhibits a volumetric symmetry‚ a handy relationship known as Gauss’s Law may be used to calculate the charge distribution of the volume. The charge volume of a ball or rod mill is expressed as the percentage of the volume within the liners filled with balls or rods. When the mill is stationary‚ the charge

The Rutherford Model of the Atom 1. In 1911 Rutherford proposed the nuclear model of atomic structure. He suggested that an atom consists of a central nucleus (where most of the mass of the atom is concentrated) having a positive charge‚ surrounded by moving electrons carrying negative charge. Geiger and Marsden carried out an experiment to verify his proposal. The Geiger/Marsden a Particle Scattering Experiment 1. The apparatus is illustrated in the diagram below. | 2. The apparatus

Sameera Raziuddin Latent Heat of Fusion April 11‚ 2011 Abstract: A calorimeter‚ water at room temperature‚ ice‚ and a Pasco GLS Explorer were used in combination with a known value of the latent heat of fusion to create and carry out an experiment to determine the mass of an unknown amount of ice. Using the formula for latent heat of fusion‚ the mass of the ice was calculated to be 45.76g. The error of the carried out experiment was calculated to be 20.06%. Introduction:
