An Arrangement to Ensure Optimum Temperature of Traffic Police Booth K. Augustine Babu and P. Sherjin Department of Mechanical Engineering‚ Sri Ramakrishna Institute of Technology‚ Coimbatore‚ Tamil Nadu‚ India Abstract The temperature of the traffic police booth is found to be at an elevated level during hot sunny days‚ which may cause discomfort to the person who is standing under it. Lowering this high inside temperature of the booth is the central theme of this work. Semi-conductor

I am going to investigate the enthalpy change of combustion for the alcohol homologous series. I will investigate how alcohols with increasing number of carbons affect the enthalpy change when an alcohol goes under combustion. The energy that alcohols release when being used is called the enthalpy change of combustion. This is defined as "Standard enthalpy change of combustion‚ is the enthalpy change when one mole of a substance burns completely in oxygen under standard conditions (298K‚ 100 KPa

Enthalpy change of magnesium in combustion Rui Shen Chemistry 4U – Ms .Brazier 2/28/2013 Introduction: Hess ’s law is a terminology in chemistry named after Germain Hess‚ a Swiss-born Russian chemist and physician who published it in 1840. The law states that the total enthalpy change during the complete course of a reaction is the same whether the reaction is made in one step or in several steps. Enthalpy cannot be directly measured‚ but rather the change in enthalpy. Enthalpy is described

Title: Study of Solubility Equilibrium Abstract The effect of temperature on the solubility product constant‚ Ksp‚ of potassium hydrogen tartrate in water was investigated in the temperature range of 285K to 318K at normal atmospheric pressure. It was found that the solubility of potassium hydrogen tartrate decreases with a decrease in temperature and consequently a smaller volume of sodium hydroxide is needed to neutralize it. The molar solubility of potassium hydrogen tartrate was calculated

DIFFERENT STORAGE TECHNIQUES FOR FRUITS AND VEGETABLE Food spoilage: Every change in food that causes it to lose its desired quality and eventually become inedible is called food spoilage or rotting. Factors affecting storage life The natural limits to the post-harvest life of all types of fresh produce are severely affected by other biological and environmental conditions: Temperature: An increase in temperature causes an increase in the rate of natural breakdown of all produce as food reserves
