struggling to complete my assignments and daily tasks. I had no idea how much the caffeine helped me throughout the day. These side effects were not expected. I am starting to feel like my schoolwork will suffer because I cannot complete a full assignment of reading. In regards to my social life‚ I do not have one anymore. I have not felt like going out or talking too much with others. I am aware that the lack of caffeine my not be the only reason for the way I am feeling‚ since the first trimester of

LAB REPORT 4 DETERMINING AN EQUILIBRIUM CONSTANT CAUSION 1. Potassium thiocyanate (KSCN) is hazardous 2. Wear protective material before performing the experiment. INTRODUCTION This experiment outlines the techniques necessary to determine the equilibrium constant for the formation of an iron(III) thiocyanate complex ion (FeSCN2+) from Fe3+ and SCN- . The quantitative preparation of several solutions and subsequent measurement of the solution absorbance

Introduction The aim of this experiment was to determine the effect of caffeine on resting body temperature. This has to do with homeostasis‚ which is the maintenance of equilibrium. In other words‚ it is a stable body state. Homeostasis refers to the process of keeping the internal body environment in a steady state‚ when the external environment is changed (Homeostasis 2). Humans are warm-blooded creatures that generate body heat internally and maintain body temperatures at a fairly constant level

Determining g on an Incline Lab #1 Theory: During the early part of the seventeenth century‚ Galileo experimentally examined the concept of acceleration. One of his goals was to measure the acceleration due to gravity‚ or the acceleration of freely falling objects. Unfortunately‚ his timing devices were not precise enough to measure the free fall time directly. He decided to “dilute” gravity by using fluids‚ inclined planes‚ and pendulums. Galileo’s idea of diluting gravity using inclined planes

Title of Experiment: Pressure distribution on an aerofoil Aim: The aim of this experiment is to examine the pressure distribution on an aerofoil and its variation with incidence. Introduction: An aerofoil is the two-dimensional cross section of a wing‚ tail or helicopter rotor blade. The lift and pitching moment on an aerofoil is determined by the pressure distribution on it. The pressure distribution changes with the angle of incidence. Understanding the behaviour of aerofoils requires some

Introduction A. Attention Getter: If you drink some kind of caffeine on a daily basis or close to that often‚ please raise your hand. Those you without your hands raised make up a rare percentage of today’s Americans. An article published in the Chicago Tribune on October 19‚ 2011 by Julie Deardorff‚ stated that nearly 90% of Americans drink coffee on a regular basis. B. Relevance Statement: When asked if you drank coffee or another source of caffeine regularly‚ the majority of the class raised their hand
