    The Effect of Varying Temperatures to the Rate of Respiration of Bufo marinus Statement of the problem: At which environmental temperature‚ do toads have the highest respiration rate? Most animals obtain oxygen‚ which comprise 21% of the air‚ from the environment. Oxygen combines with hemoglobin of the blood to form oxyhemoglobin. Oxyhemoglobin is transported to the tissues where oxygen is released and used for the metabolic functions of the animal. The functions produce waste materials‚ such

    project is on the surface tension of water and what affects the surface tension of water. The question that I am going to ask is how does temperature and salinity of water affect the surface tension of the water. My hypothesis is that the colder and the saltier that the water is‚ the stronger that the surface tension of the water will be. Some of the background research that I have done has explained to me that the surface tension of water is a property of a liquids surface that can cause it to

    Abstract This experiment is to study the effect of temperature on the rate of reaction between potassium permanganate with oxalic acid. We used 2cm3 of 0.02M potassium permanganate and 4cm3 of 1M sulphuric acid into a test tube. In another test tube‚ we placed 2cm3 of oxalic acid. We placed the test tubes in a water bath at 40‚ 45‚ 50‚ 55 and 60oC respectively. When the solutions have attained these temperatures pour the oxalic acid into the acidified permanganate solution and recorded the time

    Kinetics Factors Affecting Reaction Rate OVERVIEW Chemical reactions occur at different rates. In this experiment you will consider some of the key factors that influence the rate of a reaction: ƒ ƒ ƒ ƒ nature of reactants - particle size temperature concentration catalysts According to the collision theory‚ the rate of a reaction depends on the frequency of collisions between reacting particles. The more frequent the collisions‚ the faster the rate of the reaction. However‚ in order for the collisions
