Experiment to Find Out Which Fuel Produces Most Energy Aim === My objective in this piece of coursework is to determine which of five fuels produces the most energy and if the energy production relates to the amount of carbons.. The fuels are Ethanol, Propanol, Propan-2-ol, Butanol and Butan-2-ol. Setting up the practical. Because there are some restrictions on the time we are going to have to perform the experiment, we are first going to find out a set up that would allow us
Finding Out Which Fuel Releases the Most Energy Per Gram Aim: To find out which fuel releases the most energy per gram. Scientific Theory: Heat is the transfer of energy between two objects due to a temperature. Heat is lost through the atmosphere because of combustion a process where a substance and oxygen or other elements combine to produce heat and light (fire). Combustion of alcohols produces water and carbon dioxide. Therefore the amount of heat which is not being used to heat
collision. Hypothesis It was hypothesized that after the two disks come into contact in the head-on collision, the total momentum and kinetic energy would be conserved. In the glancing collision, it was also hypothesized that the total momentum would be the same before and after the impact. Additionally, the kinetic energy would not be conserved because some of the energy is transformed into another form. The results for the final two-dimensional would be similar to the second collision. Related Theory
ball bounce better, it also makes it bigger. More energy is absorbed when the ball is hot; the ball also expands when it gets hotter. A ball bounces better if it is inflated because there are more molecules, so the ball has more spring energy, when it bounces the energy is absorbed into the ball to spring it back up. If the ball bounces on a hard surface the energy is absorbed into the ball and if the ball bounces on a soft surface the energy is absorbed into the surface. If a ball is used to

that have shaped our understanding of the working world. TOTAL ENERGY OF THE SYSTEM AND IT'S SURROUNDINGS IS CONSTANT or ENERGY IS CONSERVED, Brings back that long established idea that nothing can be created or destroyed. How do we know this? This is an empirical law, which means that we know that energy is conserved because of many repeated experiments by scientists. It's been observed that you can't get any more energy out of a system than you put into it. Latent heat Latent Heat
chain of elastic components, they are not as far past optimum length therefore allowing a greater force over the initial phase of their shortening range, with the stretching of sequences of elastic components, this then causes the storage of elastic energy that is then reutilized in the propulsion phase (Ettema et al. 1992).

of wire. Resistance is a force, which opposes the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit Key factors: - Thickness of the wire: if the wire is thin, the electrons are forced to travel through a smaller area, therefore colliding more frequently, resulting in them giving up more of their energy to surrounding particles. - Temperature: resistance of the wire increases as the temperature increases

the corer. Then collect a cylinder of beetroot by pushing the corer into the beetroot and withdrawing it. The cylinder remains inside the corer- so push it out with the end of a pencil. · Collect 3 cylinders, and then cut them into 6 pieces of 3 cm with a segregated knife. · The beetroot was cut to 1cm. Because the beetroot has been cut some of the cell membranes had been broken, which means some anthocyanin will leak out. This must be completely washed off in order to maintain the reliability
Between Light Intensity and the Rate of Photosynthesis Investigate the relationship between light intensity and the rate of photosynthesis. Photosynthesis is important because animals eat food, as it is a source of energy. All living things need a constant supply of energy if they are to grow, reproduce or move. Plants do not eat food but they do have some in the form of starch in their leaves. The symbol equation for photosynthesis is: 6 CO2+6 H2O-light C6 H12 06+6 02. There are
photosynthesis will be larger. Plants can absorb and use light energy because they have a green pigment, chlorophyll, contained in the chloroplasts in some of their cells. Chlorophyll allows the energy in sunlight to drive chemical reactions. Chloroplasts act as a energy transducers, converting light energy into chemical energy. So as the plant has more light the chlorophyll inside the chloroplasts can react faster absorbing in more light for food and energy. The equation for photosynthesis can help to predict
Investigating Which Alcohol is the Best Fuel AIM: I am carrying out an investigation to see which alcohol is the best fuel. I will do this by experimenting with different alcohols and setting them alight and measuring different factors. I will analyse all my results and try to discover patterns, which should help me to conclude which alcohol is the best fuel. PLAN ==== This is how my experiment will be set out: ========================================== Keeping this
Will A Slinky Travel Faster Down Stairs After Adding Mass? Joseph Evans Intro to Physics ABSTRACT The purpose of the experiment was to see if adding mass to a slinky affected how fast it traveled down the stairs. From the background research, it was hypothesized that adding mass to the slinky would make it travel down the stairs slower. This was hypothesized because adding mass to each side of a slinky would cause more force to be needed to pull the slinky over. To perform the experiment the following
wrong, because it would take different amounts of energy to heat different volumes of water - The distance from the bottom of the calorimeter to the top of the wick. Otherwise different amounts of energy could escape each time making it an unfair test. Plan: From carrying out the follow experiment I will be able to find out the enthalpy change of each fuel I am testing. The enthalpy change of combustion of a fuel is the measure of energy transferred when one mole of fuel burns completely
elastically, i.e., without change in energy. A small fraction of light is scattered inelastically with frequencies I ± m, where m are the characteristic vibrational frequencies of the e- cloud in the molecule/solid. Figure. 2.8 Schematic view of the elastic and inelastic processes in a material with incidence of light. The spectral bands with frequencies I-m are called Stokes Raman bands whereas and those of I+m are called anti-Stokes. Thus the energy differences between the incident and
using proton and lithium ion conducting solid electrolytes have received considerable attention recently and several supercapacitor modules have been fabricated using polythiophine, polypyrrole, polyaniline and their related composites to achieve energy storage of about 200F/g. Generally the voltage of a super capacitor is dictated by the available potential window prior to the commencement of any irreversible anodic and cathodic faradaic processes. The range with aqueous systems is about
Planning I am going to investigate respiration in crickets and how temperature varies the rate of respiration. The calculation for aerobic respiration is: [IMAGE]Oxygen + Glucose Carbon dioxide + water + energy [IMAGE]6O2 + C6H12O6 6CO2 +6H2O + (J) I will do the experiment safely by making sure that the water will not be too hot or too cold, this is a safety precaution for me as well as the crickets. As we don't want to cause the crickets too much
