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
Investigating Factors that Affect the Amount of Heat Produced in Neutralisation I am going to investigate factors that affect the amount of heat produced in neutralisation. My objective is to plan and conduct an experiment from which I should be able to draw a firm conclusion that will either prove or disprove any predictions I have made. The factor I will be investigating is concentration
Investigating Rates of Reactions My aim is to investigate what factors affect the rate of reaction between magnesium and hydrochloric acid. The factor that I will be focusing on is the concentration of Hydrochloric acid. [IMAGE]Reaction Equation: Mg (s) +2HCl (aq) = MgCl2 (aq) +H2 (g) Magnesium + Hydrochloric Acid = Magnesium Chloride + Hydrogen There are several different variables you can such as temperature, concentration; surface area and whether or not to use a catalyst or not
Investigating Factors Affecting the Heat of Combustion of Alcohols PLANNING SECTION Introduction ------------ Alcohols are organic substances, and consist of Hydrogen, Oxygen and Carbon. All alcohols are toxic but the amount that can be tolerated by the human body varies for different alcohols. For example drinking small amounts of Methanol can lead to blindness and even death. Ethanol is the only alcohol that can be drunk safely and is found in all alcoholic drinks. Throughout this
Investigating Osmosis in Potato Chips Planning Introduction: the definition of osmosis is the movement of water particles from a weaker solution to a stronger solution through a partially permeable membrane. Aim of investigation: I am trying to find out how external concentration of liquid surrounding a potato chip affects it - does it increase or decrease in mass etc. Method, diagram and equipment: Diagram of experiment Equipment · 5 Boiling tubes · weighing scales
Investigating Osmosis in Potato Tissue Aim-We are going to investigate how 'osmosis' is effected by higher and lower concentrations of water using potato cylinders as selectively permeable membranes. A selectively permeable membrane is something only water molecules can pass through. We will cut eighteen potato cylinders to the same width and length using a scalpel and a corer on a white tile. We shall use the same potato for each cylinder. The cylinders should then be around the same
Investigating Factors Which Affect The Reaction Between Chalk and An Acid Introduction: Chalk is just one of many forms that calcium carbonate can take. It is made of the mineral remains of sea creatures from millions of years ago. It is quite soft, but solid. It reacts with hydrochloric acid like this 2 CaCO3 + 2 HCl → CO2 + CaCl2 + H2O producing Carbon Dioxide, which is what we measure in the experiment. There are different factors affecting the rate of this reaction, such
Investigating Factors that Affect the Rate of Photosynthesis in Elodea Aim: To find out which factors affect the rate of photosynthesis in Elodea. Variables: The variables that might affect the rate of photosynthesis in this experiment are: Temperature: When the temperature rises so does the rate of photosynthesis; this is because as the temperature around the plant rises the enzymes controlling photosynthesis inside the chloroplasts heat up and start moving around faster, the fast
Investigating Photosynthesis in Canadian Pondweed Aim The aim of the investigation is find out what factors affect the rate of photosynthesis. Photosynthesis should not occur if one of the limiting factors is not present. Plan ==== The factors affecting photosynthesis are: Light - This will affect photosynthesis because it is one of the limiting factors. Without light photosynthesis can't take place as it is the energy source. Temperature
Investigating Factors that Affect Heat Loss PROBLEM ======= I have been asked to investigate the link between colour and heat loss. Does the silver or the black cup lose its heat faster? HYPOTHESIS ========== I think that the black cup will lose heat faster than the silver cup because black absorbs heat, then releasing it out of the cup into the surrounding air and surface, where as the silver cup will reflect the heat back into the cup therefore keeping the water hotter for
Investigating Factors Affecting Resistance of a Wire Aim --- Investigate what factors affect the resistance of wire, however in this experiment I am going to monitor how the length of a wire affects the resistance of a wire if the current is kept the same. Method ------ 1) Arrange apparatus as shown in the Diagram: 2) Cut a length of wire over a meter long and sellotape to a meter ruler. 3) Attach one positive crocodile clip to 0cm, and move the negative up/down, stopping
Investigating Osmosis in Potato Tissue Aim To estimate the concentration of sucrose in potato tissue. Hypothesis ========== I believe that the potato tissue that has been in the hypotonic (0.1M sucrose) solution will be more turgid than before, while the tissue in the isotonic (0.3M sucrose) will be similar to its previous state. The tissue that has been in the hypertonic (0.5M sucrose) should be far more placid than it was before. This is because of osmosis - water diffusing
Investigating Rate of Reaction between Iodide ions and Peroxodisulphate ions with respect to Temperature and use of a Catalyst Introduction The aim of this experiment was to investigate the affect of the use of a catalyst and temperature on the rate of reaction while keeping all the other factors that affect the reaction rate constant. In the reaction, potassium peroxodisulphate and potassium iodide will be used to provide the peroxodisulphate ions and iodide ions respectively. The ionic formula
Investigating Factors that Affect the Rate of Reaction Between a Metal and an Acid Factors that may affect the experiment + fair test The variables that could affect the rate of reaction are the temperature, amount of magnesium, concentration of acid, surface area of magnesium and volume of acid. The variable I am going to change is the concentration of acid. I am going to measure how long it takes a piece of magnesium(no more than 20m in length) to react in different concentrations of
Investigating Osmosis in Potatoes Preliminary Experiment Aim The aim of this experiment is to determine the solute concentration of potato tissue; i.e. To investigate at which point the sucrose concentration is the same as the solute concentration inside the potato (an equilibrium is reached) Introduction Osmosis is the movement of water molecules from an area of high concentration; (a weak solution), to an area of low concentration; (a strong solution), through a partially permeable
Investigating Factors that Affect the Rate of Reaction There are certain factors which affect the rates of reaction in an experiment. These factors are: · Pressure · Temperature · Concentration * Surface area / particle size and * The addition of a catalyst The factors that I will be concentrating on are temperature, concentration and surface area / particle size. Pressure Pressure influences the rate of reaction only when the reactants are in their gas phase. Pressure
Investigating Osmosis in Potatoes Aim: Investigate the movement of osmosis through a selectively permeable membrane, in this case potato. Introduction: Osmosis is the movement of water through a semi permeable membrane. The water passes from an area of high concentration to an area of low concentration, until the two concentrations are equal in concentrations of water. Many cell membranes behave as semi permeable membranes, and osmosis is a vital part in the movement of liquids

Investigating Rate of Reaction Aim I am going to investigate the rate of reaction between calcium carbonate and hydrochloric acid. I will look at the various factors affecting the reaction and select one variable to change, while the others keep constant
Investigating Osmosis In A Potato Introduction: "Osmosis is typically defines as the flow of one constituent of a solution through a membrane while the other constituents are blocked and unable to pass through the membrane. Experimentation is necessary to determine which membranes permit selective flow, or osmosis, because not all membranes act in this way. Many membranes allow all or none of the constituents of a solution to pass through; only a few allow a selective flow. In a classic
