Plan: Aim: The enthalpy change of combustion of a fuel is a measure of the energy transferred when one mole of fuel burns completely. A value for the enthalpy change can be obtained by using the burning fuel to heat water and using fact that 4.2j of energy are required to raise the temperature of 1g of water by 1oC. In this investigation my aim is to find the enthalpy change of combustion of a number of alcohols so that I can investigate how and why the enthalpy change is affected by the molecular

ABSTARCT: Tensile tests are fundamental for understanding properties of different materials‚ and how they will behave under load. These properties can be used for design and analysis of engineering structures‚ and for developing new Materials that better suit a specified use. This lab tested two materials mild steel and cast iron. The data from each test was used to determine valuable material properties such as ultimate tensile strength‚ modulus of elasticity‚ and yield strength. Other calculated

SUPPLEMENTARY MATERIAL I Unit V: States of Matter 5.7 KINETIC ENERGY AND MOLECULAR SPEEDS Molecules of gases remain in continuous motion. While moving they collide with each other and with the walls of the container. This results in change of their speed and redistribution of energy. So the speed and energy of all the molecules of the gas at any instant are not the same. Thus‚ we can obtain only average value of speed of molecules. If there are n number of molecules in a sample and their individual

that salicylamide has large electron density at the para and ortho positions. These sites are more likely to undergo the iodination‚ which supports the answer from question #1. 3. The ortho product has an energy of -145.38 KJ/Mol while the para product has an energy of -164.74 KJ/Mol. The lower energy of the para product makes it more favorable for its formation. This shows that the para product is more favorable due to its lower energy. This supports #1 because it shows that the para product is both

Zinc Tris-thiourea Sulfate (ZTS) is a Semi Organic Nonlinear Optical (NLO) material which finds applications in the area of laser technology‚ optical communication‚ data storage technology‚ and optical computing etc. The author has successfully grown ZTS crystal by gel method. Gel technique has been adopted at ambient temperature to attain better result. The grown crystals were transparent and colourless. The crystal size has been obtained the range about 5mm X 3mm X 2mm. Thermal study of ZTS crystal

Aim: The aim of this experiment is to determine which fuel‚ out of Pentane‚ Propane-1-ol and Propane-2-ol would be the most appropriate to take on a camping trip to a national park where wood cannot be used to burn. Factors that need to be considered are: • Heat of combustion (flash point) • Heat of vaporisation (boiling point) • How long the fuel will last • Does the fuel heat up the water relatively quickly • Does the fuel combust completely Hypothesis: If the tests are all successful‚ Pentane
