    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 Tissue

    2597 Words  | 6 Pages

    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

    856 Words  | 2 Pages

    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

    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

  • Photosynthesis Lab Report

    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

    1607 Words  | 4 Pages

    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

    815 Words  | 2 Pages

    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 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 Osmosis In A Potato

    3353 Words  | 7 Pages

    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
