Fuels Investigation Aim: To find out which fuel gives out the most energy. Planning We will be using 6 different fuels to heat up 100ml of water‚ and find out the changes of the temperature. We will measure the temperatures of the water before and after the experiment. We will burn heat the water for exactly 2 minutes‚ and check the changes in temperature. The change in temperature will allow us to work out the energy given off the fuel by using this formula: Mass of water x 4.2 (water’s specific

Chemistry design: Fuel energy lab Research question: What is the energy density of cyclohexane‚ and how does it compare to the energy density of normal hexane? Variables: Independent variable – The independent variable in this experiment will be the type of fuel that will be used. This will be either Hexane or Cyclohexane. Each type will be given to us and labelled so it will be quite simple to control this variable. This cannot be measured using any apparatus so the lab assistant must be entrusted

Fuel and energy-Why are fuel and energy important? I chose this topic because I think; it plays an important role in our life. Without fuel and energy‚ I wouldn’t be able to arrive to school on time‚ because I need to come to school by car‚ which would not work if there is no fuel. I wouldn’t be able to use Air Conditioner‚ because it need electricity to works….and many more example. The point is without fuel and energy‚ most part of our life would be meaningless. So it is important for us‚ that

Energy content is an important property of food. The energy your body needs for running‚ talking‚ and thinking comes from the food you eat. Energy content is the amount of heat produced by the burning of 1 gram of a substance‚ and is measured in joules per gram (J/g). Usually‚ fat-rich foods like peanuts and cashews provide more energy than just carbohydrates like marshmallows. You can determine the energy content by burning a portion of food and capturing the heat released to a known mass of

Work Investigation Purpose: In this lab‚ you will work with a partner to investigate the force required to do work on an aluminum plate as you pull it at different angles. Materials: 1 aluminum plate String 1 kg mass (you might need to use two 500-gram masses) 1 spring scale Prediction: Before you begin‚ sketch a graph that shows your prediction of the relationship between the force and the angle you pull it at. In other words‚ what patter do you think the graph will demonstrate? Procedure:

We will also identify units of measuring heat such as calories and joules. We will use basic lab equipment provided in our labpaq and we will use several household items as well. We

assess personal energy use and speak about the forms of energy that I currently rely on and the sources they originate from. It also talks about renewable energy sources that would be most and least appropriate to use in a certain location. Then it refers to the advantages and disadvantages of the energy source that I currently use‚ also about renewable ones that have been identified. The last part of the paper addresses energy conservation and its impacts on the environment. Energy is embodied in

Energy and Fossil Fuels January 30‚ 2012 I will be covering different types of energy and how they are converted into other forms of energy. I will also discuss what fossil fuels are‚ alternatives to fossil fuels and the advantages and disadvantages of alternatives. There are several different forms of energy and how it can be converted from one type to another. According to The Law of Conservation of Energy; energy can neither be created or destroyed‚ only transferred

Beanium Investigation The purpose of this investigation was to find the average atomic mass for the element Beanium with three isotopes. The average atomic mass is the average mass of the atoms of the element divided by the total number of atoms. An isotope is an atom with the same number of protons‚ but different number of neutrons; they are different forms of a single element. Since we knew the isotopes had almost the same amount of sub-atomic particles‚ we made our hypothesis the following:

Qualitative Chemical Analysis of Energy Drinks and Other Beverages - Lab Report Discussion and Analysis As a result of conducting various qualitative chemical analysis tests‚ Monster Energy ® was found to contain a large amount of reducing sugars and NaCl. It was found to be void of proteins and lipids. Further‚ Canada Dry ® gingerale was found to contain a large amount of reducing sugars‚ while being void of protein‚ lipids and NaCl. The components of the Monster Energy drink tested were quite congruent
