    IB Chemistry Lab Report Design Example— Effect of Temperature on Solubility of Potassium Chloride in Water Research question How does temperature affect the solubility of potassium chloride in water? Hypothesis As the temperature of water increases‚ the particles of solid Potassium chloride‚ KCl‚ which are absorbing energy from its surrounding‚ start moving more easily between the solution and its solid state because. According to the second law of thermodynamics‚ the particles will

    Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

    Temperature affects enzymes in two different ways: by increasing the kinetic motion of molecules‚ changing the rate of collisions between them and the hydrogen bonds it’s 3D structure(D. Fraser‚ 55). There is a specific temperature for every enzyme where activity is maximized‚ and also where an enzyme becomes denatured. An enzyme becomes denatured when it is heated at extreme temperature; the excessive kinetic movement of the amino acid begins

    level of the temperature in human body‚ or How/Which factor affects on Homeostasis. Research statement: Factors affecting on the internal temperature of the human body. Purpose of investigation:To find out which all factors affects on the steady level of temperature in human body. My factor is that external/environmental temperatgure affects on the internal temperature of the body. Hypothesis: Environmental temperature affects on the internal temperature of our body. When external temperature is low internal

    Aim: The aim of the experiment is to test the effect temperature has on the activity of the enzyme rennin. Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC‚ which is the body temperature‚ where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the enzyme will stop working. Introduction:Enzymes are

    combined with baking soda. Then the temperature was taken‚ and finally calcium chloride was added‚ which formed a chemical reaction. Our lab question was how does the amount of calcium chloride affect the temperature of the product? We chose our independant variable to be the amount of calcium chloride added to the water/baking soda mixture. We had the dependant variable be the ending temperature. My hypothesis is IF we add more calcium chloride‚ THEN the temperature of the product will rise‚ BECAUSE

    Is There A Relationship Between Body Temperature and Heart Rate? Statement of Research Question: This study sets out to determine whether there exists a difference in the average body temperature between males and females. Furthermore‚ the study aims to determine whether an increase in heart rate corresponds with an increase in body temperature. Data Collection: The data was obtained from the article “What’s Normal? -- Temperature‚ Gender‚ and Heart Rate” (Shoemaker‚ Allen 1996) as found in

    experiment was designed to study the effect of exercise on skin temperature and heart rate. Studying the effect of exercise on skin temperature and heart rate yields understanding of how homeostasis is achieved in humans. This knowledge creates opportunity to discover more effective ways to return the human body to optimal functioning‚ rather than a reliance on natural processes. This experiment measured the change in skin temperature and heart rate of a chosen subject for four two-minute intervals

    rate. The hypothesis also proposed that as temperature increases the speed of the reaction would decrease‚ this is evidenced in graph 7 which shows a negative decrease in time as the temperature of the solution increases. This decrease can be modelled by the exponential formula T=12.9e-0.0249t. The raw data collected suggests that directly increasing the concentration of potassium iodate decreases

    Abstract I found that this experiment gives me an understanding on how osmosis and diffusion works. In its simplicity‚ it explains the process that our bodies (mainly cells) use all the time. It also showed me that even with the temperature changing‚ it doesn’t drastically change the rate of diffusion. Introduction Diffusion is important in all living systems. Osmosis is the passage of water from a region of high water concentration through a semi-permeable membrane to a region of low water
