Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

Miami Heat In this essay I will discuss three things about the Miami Heat (my favorite team). The first thing I will discuss is why I chose this topic. The second thing I will discuss about the Miami Heat is what I already know. The third and final topic I will discuss in this essay is what I want to find out about the Miami Heat. These are the topics that I will discuss in this essay. Why I Chose My Topic: Ever since I was young I’ve always loved

3rd Year Thermodynamics Lab Report Mechanical Engineering Science 10 Forced Convection (in a cross flow heat exchanger) Summary The aim of this lab is to determine the average convective heat transfer coefficient for forced convection of a fluid (air) past a copper tube‚ which is used as a heat transfer model. Introduction The general definition for convection may be summarized to this definition "energy transfer between the surface and fluid due to temperature

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity

Heat can be described as the increase in temperature until it becomes intolerable or unbearable. In literature‚ many authors use heat as a symbolic device to represent elements such as love‚ confusion and anger. In The Great Gatsby‚ Fitzgerald also uses the sweltering heat to enhance the mood and setting of the novel. The novel starts in spring but the climax occurs during the hottest days of the summer. In this essay‚ I will attempt to show that Fitzgerald effectively uses heat to show the passion

Aim: Perform an experiment to determine the latent heat of fusion for milk. Materials: Calorimeter Celsius Thermometer Platform balance Kettle Milk ice cubes Stopwatch Hot Water Procedure: The copper cup was weighed and its mass was then recorded. The kettle was then used to boil water and this water was poured into the copper cup. The mass of the cup plus the hot water was calculated and recorded. The copper cup was then placed in the insulated container. The water’s temperature was

between placid surface and hidden corruption structures The Big Heat‚ and the drama deals with a struggle between those forces which try to keep the lid on and those which want to force the hidden violence out into the open" (Tom Gunning). Discuss this claim in relation to the film. Somebody ’s going to pay because he forgot to kill me‚ this was the tagline featured on the poster for Fritz Lang ’s dark film noir classic The Big Heat which establishes the films undercurrents of violence and revenge

content of food) Lab report Introduction We‚ human needs energy to live and for movements. Thus‚ we eat and combust food to release its heat energy in our bodies. In this experiment‚ we will determine how much heat energy released when we eat snack foods such as popcorn or potato chips. This lab includes three burning tests of different foods with different energy contents. Calorimetry is the science associated with determining the changes in energy of a system by measuring the heat exchanged with

In the 1995 Chicago Heat Wave‚ mortality was related to living alone in that living along doubled a person’s chance of not surviving the heat wave. On the other had‚ and form of social connection lessened the chance of dying. Some of the main reasons that this relationship exists are because most of the people living along were older people and increasingly people with poor mobility were living alone. Living alone as an aging person was thought to be the ideal way for them to live because it gave
