Temperature is one of the weather elements and measures the degree of hotness and coldness in a place. The temperature of a place is affected by a number of factors such as latitudinal location‚ seasonal variations‚ albedo of the place‚ contrasts between land and sea and elevation. Latitudinal location has the strongest influence on the climatic conditions on a macro/global scale. The rest of the factors then serves to modify these influences and are secondary‚ operating at a smaller scale. Latitude

Effect of Temperature on Solubility Lab Purpose: What is the solubility of minerals in water? What is the relationship between temperature and solubility? Hypothesis: If salt and sugar are each tested in water of varying temperatures‚ then salt and sugar’s solubility will increase as the temperature also increases. Materials: Two 250 mL beakers Tap water 100 mL graduated cylinder Hot plate Two petri dishes Glass stirring rod Salt Sugar Thermometer

Each enzyme has it optimum temperature range at which it functions at an optimum efficiency. In this experiment‚ Rennin might have an optimum temperature of 37 degrees Celsius as it is found in the stomachs of young mammals. As the temperature is increased‚ the rate of reaction (time for milk to curdle) will also increase until the optimum temperature is reached (37 degrees). After reaching this set point‚ the activity of the enzyme will gradually begin to decrease and the rate of reaction will

THE EFFECT OF TEMPERATURE ON CATALASE RESEARCH QUESTION: What is the effect of various temperatures‚ 0°C‚ room temperature‚ 37°C‚ 50°C‚ 60°C‚ on the number of oxygen gas bubbles liberated‚ in a decomposition reaction between the enzyme Catalase‚ obtained from crushed mung beans‚ and 2% of the substrate Hydrogen Peroxide? INTRODUCTION: Enzymes are biological catalysts that increase the rate of chemical reactions without they themselves being involved in the reaction itself. Enzymes are proteins

Results The diameter of the cylinder (D) is 0.01m and the length of the heater (L) = 0.07m. The emissivity of the surface was 0.95 and the Stefan Boltzmann constant was 56.7x10-9 Wm-2K-4. The room temperature was assumed to be 25°C which is 298.15K. At a trendy east London bar‚ a group of body hackers are putting forward their reasons for human augmentation to a packed audience of mainly under-35s‚ many of whom are sporting piercings and tattoos. Putting a chip under your skin is not so very different

Temperature affecting enzyme activity Aim: To see how temperature can affect enzyme activity Prediction:-I think the one that will work best will be the rennin placed in milk at 37oC My independent variable will be the temperature My dependant variable will be how thick the milk becomes The equipment I need is milk‚ 5 test tubes‚ rennin‚ water bath‚ boiled rennin‚ a glass rod and a stopwatch Introduction: Rennin is an enzyme found in the stomach‚ its function is to solidify milk. We

Temperature Affecting Enzyme Activity Introduction The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life’s processes would not come so easily. Enzymes are basically proteins‚ which have specific shapes for different substrates. Enzymes change the rate in chemical reactions. It does this without having to change its own shape‚ which makes enzymes different from other proteins. A common enzyme that we have is catalase‚ which breaks down

project is to demonstrate how water temperature affects the dissolving of sugar in liquid. Everything in our universe is made up of particles which are in constant motion. In a solid state particles move the slowest while in a liquid state particles move the fastest. Under the right conditions‚ solid particles (the solute) when mixed in liquid (the solvent) can form a solution. This occurrence is called dissolving. I wanted to answer the question; does the temperature of water affect the speed at which

The effect of temperature on a reaction rate In this experiment I shall be investigating how temperature affects the rate of reaction Rates of reaction The Factors that affect the rate of reaction are temperature‚ surface area‚ concentration‚ catalysts‚ light and pressure Surface area – Surface area is the amount of solid surface that is available for reaction - Only affects solids so this will not affect our

is the temperature at which water changes phase from a liquid to a solid or vice versa. The freezing point describes the liquid to solid transition while the melting point is the temperature at which water goes from a solid (ice) to liquid water. In theory‚ the two temperatures would be the same‚ but liquids can be super cooled beyond their freezing points so that they don’t solidify until well below freezing point. Ordinarily the freezing point of water is 0° C or 32° F. The temperature may be lower
