Extended Experimental Investigation Generating Electricity Physics Teacher: Mr Heagney By: Jesse O’Sullivan Background Information: The history of electrisity leads right back to more than two thousand years ago. Ancient Greeks discovered that rubbing fur on amber caused an attraction between the two. Many electricity-related discoveries had been made by the 17th century‚ including the differentiation between negative and positive currents‚ the classification of matireals as conductors

be used in this EEI. The purpose of this EEI is to test the rate in which lipase reacts to different variables such as temperature and pH. Enzymes are found in foods‚ epically raw foods such as meat‚ but cooking foods destroys any enzyme activity‚ including lipases. If the temperature changes then the pH levels will change. The optimum temperature is 37°‚ that is the average temperature inside the human body; the optimum pH level is 8.0. (Corporation‚ 2013) The purpose of this EEI and experiment

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

mixed with a lower non-isomeric parent chain alcohol produce more heat? Table of contents N/A This EEI report addresses the claim that when alcohols are mixed with a lower non-isomeric parent chain alcohol‚ they will produce more heat. This was the basis of the experiment and the hypothesis that inspired it. Background Alcohols are a common substance found in everyday life. From petrol to spirits‚ alcohols are a substantial product used in normal everyday life. Alcohols range from a percent chain

Mass of fuel burned = 0.87g Start temp = 19oC Finish temp = 23oC‚ Temp rise = 4oC Following the pilot experiment I made some minor adjustments: Height of can above wick down to 4cm to improve contact with flame and stir the water‚ because the rise in temperature is too little.

He used a spirit burner containing ethanol to heat 250g of water in a beaker. The temperature rose from 15oC to 31oC. During combustion‚ the burner lost 0.90g in mass‚ due to the ethanol combusting. Calculate the heat of combustion in ethanol. 7. The heat of combustion of ethanol is 1367 kJmol-1. Calculate the theoretical mass
