reaction is a exothermic reaction‚ when the heat released by it is absorbed by water‚ the temperature of the water increases. The heat produced by the reaction can be calculated if it is assumed that all the heat is absorbed by the water. Heat change of reaction=-heat change of water =-mH2O×cH2O×△TH2O As the water has gained the heat produced by the reaction‚ the heat change of reaction is negative when the temperature of the water increases. As the heat change observed depends on the amount of reaction

behave like sensible heat storage (SHS) materials; their temperature rises as they absorb heat. Unlike conventional SHS‚ however‚ when PCMs reach the temperature at which they change phase (their melting temperature) they absorb large amounts of heat at an almost constant temperature. The PCM continues to absorb heat without a significant rise in temperature until all the material is transformed to the liquid phase. When the ambient temperature around a liquid material falls‚ the PCM solidifies‚ releasing

these collisions the speeds and the kinetic energies of the individual molecules keep on changing. However at a given temperature‚ the average kinetic energy of the gas molecules remains constant. If at a given temperature‚ n1 molecules have speed v1‚ n2 molecules have speed v2‚ n3 molecules have speed v3‚ and so on. Then‚ the total kinetic energy (EK) of the gas at this temperature is given by where m is the mass of the molecule. The corresponding average kinetic energy ( If the following

CONCLUSION The experimentally obtained data collected for the reaction between IO3- and HSO3- at various temperatures is clearly supported by the Arrhenius equation. Referring to Graph 1.7‚ the line of best fits clearly passes through most of the data points displaying a linear relationship between temperature and the rate of the reaction. The R-squared of the graph which is a statistical measure of how close the data are to the fitted regression line is 0.9818. This number is extremely low which

Polymer Essay: Plexiglass Many of the glass screens and windows we see today are not really made of glass. They are made of plexiglass. Plexiglass is not related to the chemical structure of glass at all. It is an organic polymer. Today this polymer is used in all sorts of applications. The formation of plexiglass was begun in 1930‚ at McGi11 University by William Chalmers‚ a research student. He polymerized methacrylic ethyl ester and methacrylic nitirile‚ creating a clear plastic paste

Effect of Temperature on Solubility of a Salt Ahmed Mohammed 17-nov-2013 Abstract In this experiment‚ you will study the effect of changing temperature on the amount of solutet will dissolve in a given amount of water. In this experiment‚ you will completely dissolve different quantities of potassium nitrate‚ KNO3‚ in the same volume of water at a high temperature. As each solution cools‚ you will monitor temperature using a computer-interfaced Temperature Probe and observe

Design of sensor based fault detection system for temperature measurement using Arduino and LabVIEW Abstract This paper proposes the design of sensor based fault detection system for temperature measurement using Arduino and LabVIEW. Temperature is one of the most important industrial parameter that needs to be monitored continuously‚ any variations in the temperature from its set point causes the system to fail. The failure of any system causes many losses such as economical‚ damage to the

stable as possible. Homeostasis is necessary because human cells are efficient but very demanding. The phrase homeostasis is a bit confusing; conditions inside our bodies are not constant but are kept within a narrow range. Some factors such as temperature and blood PH change slightly while others such as blood glucose very considerably throughout a normal day without producing any harmful effects. A brief description of homeostasis is that it is maintenance of a constant internal environment in response
