Austin Vandermey GS-1140 April 4th‚ 2015 Experiment We as a society have one big problem on our hands. This problem is sleep deprivation because there are not enough hours in the day to get stuff done. Between work‚ school‚ family‚ and leisure it seems like we do not have enough time to get are daily tasks done let alone have time for sleep. It is recommended by the U.S Department of Health that people need a solid eight hours of sleep to maintain good health. I don’t know about you

Experiment #1: Introduction to Experimentation Submitted by: Neann Klara M. De Jesus BS Psychology II Submitted to: Dr. Geraldine E. Tria ABSTRACT SUMMARY The first experiment done by the class was called “Introduction to Experimentation”. Its main objective is to give basic knowledge about some of the logic of experimentation. The class was divided into groups of 2. In each group there was an experimenter (E) and a subject (S). The experimenter instructed

EXPERIMENT 5 REDOX TITRATION: TITRATION USING SODIUM THIOSULPHATE Objectives 1. 2. To prepare a standard solution of potassium iodate for use to determine the concentration of sodium thiosulphate solution accurately. To acquire the proper techniques of carrying out a titration. Introduction Redox titrations using sodium thiosulphate as a reducing agent is known as iodometric titration since it is used specifically to titrate iodine. The reaction involved is: I2 + 2Na2S2O3 I2 + 2S2O322NaI + Na2S4O6

The second goal was to measure the heat capacity of the constructed calorimeter. The third and fourth goal was to determine what reactions were to be investigated and what variations of the reactions would be studied. The two requirements that were kept in mind while creating the calorimeter were that it should be a good insulator‚ meaning that it does not allow for the transfer of heat between two systems in an environment‚ and that it should have the lowest heat capacity possible (ideally 0C) so

Swine Heat Stress ABSTRACT The purpose of this research project is to identify the effects of heat stress on swine. Heat stress is physiological distress caused by excessive temperatures usually over 80-85 degrees Fahrenheit that can result in profoundly adverse effects in swine production. The first phase of this project involves the analysis of these harmful effects on sows‚ gilts‚ and boars. Multiple journal articles will be used to establish these effects. The final phase involves

overall heat transfer coefficient on the outer surface of the covered pipe is 10 W/m2.K. if the velocity of the steam is 10 m/s‚ at what point along the pipe will the steam begin condensing and what distance will be required for the steam to reach a mean temperature of 100 oC? Question 2: Consider a horizontal‚ thin walled circular tube of diameter D = 0.025 m submerge in a container of n-octadecane (paraffin)‚ which is used to store thermal energy. As hot water flows through the tube‚ heat is

DETERMINATION OF THE HEAT OF SOLUTION BY THE VANT HOFF ISOCHORE METHOD Jan Vincent Arafiles‚ Merry Joy Arzaga‚ Anne Louise Ayson‚ Lovely Jenny Buenaflor Group 2 3A-Biochemistry chem401 laboratory ABSTRACT Thermodynamic values can be determined using the Vant Hoff isochore method. This method entails the use of equilibrium systems to determine the change in enthalpy of the solution‚ which can b related to the change in internal energy of the solution. The van ’t Hoff isochore relates

the condition in a thick walled pipe. The area for heat flow is proportional to the radius – as may be seen‚ the area at the outside wall of the pipe is much greater than the middle. As a result the temperature gradient is inversely proportional to the radius. The heat flow ‘per unit length of pipe’ at any radius r‚ is [pic] cf.

paper‚ climate change and logging. Deforestation increases the amount of carbon dioxide in the atmosphere. The carbon dioxide in our world’s atmosphere acts like a sheet of glass on a greenhouse. It lets the sunlight through but does not let all the heats back out. The continued degradation of our forest heightens the threat of global warming because the trees and other plants that take up carbon dioxide from the atmosphere to be used for photosynthesis are gone. The burning of wood or its decay contributes
