In an experiment to determine the factors affecting tensile strength in steel plates, the tensile strength (in kg/mm2), the manganese content (in parts per thousand), and the thickness (in mm) were measured for a sample of 20 plates. While you won't know until after your experiment if properties of the different liquids you choose will affect the rate at which the salt and sugar dissolve, you do know that salt crystals are generally smaller than sugar crystals. Investigating factors affecting the heart rate of daphnia class practical in the water flea daphnia , the single, small heart is easily visible when viewed under transmitted light under a low power microscope. The rate of the reaction is increased if the enzyme and substrate mixture is brought to body temperature (37 0 c) the progress of the reaction can be visualized by testing the reaction mixture for (1) the disappearance of the substrate (starch) or (2) the appearance of product (maltose.

Transpiration rates depend on two major factors: 1) the driving force for water movement from the soil to the atmosphere and 2) the resistances to water movement in the plant. - the rate law for chemical reaction among hydrogen peroxide, iodide, and acid to determine the rate law for a chemical reaction among hydrogen peroxide, iodide and acid, specifically by observing how changing each of the concentrations experiment 3 chemical kinetics objectives 1. Factors affecting the speed-rates of chemical reactions, from doc brown's science rates of reaction menu , from chemguide plop, plop, fizz fast: the effect of temperature on reaction time , from. Physical and chemical reactions - factors which affect reaction rate a total of five experiments lead chemistry pros to understand the difference between physical and chemical change they also experiment with exothermic reaction factors that affect rate of reaction.

An experiment to determine factors affecting the rate of cooldown of a hot drink pages 4 words 976 view full essay cooldown hot drink, hot drink, hold hot water. - how thickness and length affect the resistance of a wire i plan to investigate how the length and thickness of a wire affects the resistance i will do everything the same for each of the experiments to make sure it is a fair test the only thing i will be changing is the amount of insulation. Sources about osmosis - these are various papers discussing factors affecting osmosis lab experiment on osmosis - learn how experiments on osmosis are conducted in the laboratory lesson plan corner - make the teaching of osmosis interesting and relevant, a variety of lesson plans are available on this site.

This is an experiment to examine how the surface area / volume ratio affects the rate of diffusion in substrates and how this relates to the size and shape of living organisms introduction this is an a-level biology project. Reason of experiment: to investigate any one of the many factors affecting the rate of heat loss of a liquid my factor: surface area hypothesis: i hypothesis that if the base surface area of the container is increased, then the rate of cooling would be higher. In this investigation, you will design experiments to test three factors that may affect the rate of the reaction that takes place when an antacid tablet name: course: date:unit 3 lesson 6 (lesson 7 for honors)unit 3 design your own experiment: factors that affect the rate of a reaction. Part 2: affect of concentration designing an experiment a) design a simple experiment using the reaction of zinc with hydrochloric acid that will qualitatively investigate the affect of concentration of the reactants on the rate of reaction you may use any of the materials listed above in your investigation. There are a number of factors that determine the rates of reaction, listed below are the factors affecting the rate of reaction marble chips 15g main material required to determine rate of reaction, 3grams for each experiment dilute hydrochloric acid 150ml raw material required.

Before repeating the experiment, check the level of water is still 150ml (some may have evaporated) and add more water if required for different start temperatures, repeat steps 3-7 but turn off the burner at the desired temperature. Factors that affect the rate of reaction back to top some of the chemical compounds are found to be more reactive than the rest and since the change that take place between reactants are carried out in ionic forms hence the chemical reactive state is very important to determine the rate of such. An experiment is a procedure designed to test a hypothesis as part of the scientific method the two key variables in any experiment are the independent and dependent variables the independent variable is controlled or changed to test its effects on the dependent variable. Report abuse transcript of factors affecting the rate of evaporation i think this experiment could be improved by allowing a full 24 hours per experimental there are different particles in a liquid that have different energies the rate of evaporation will increase as temperature increases, surface area. Since more milk is added to a cup of coffee than a cup of tea and since milk stays warmer longer than tea or coffee a cup of tea cools down quicker than a cup of coffee.

A limiting factor is a factor that determines the rate of a reaction i will set up the experiment by filling a test tube with water and putting some pond weed in factors these four points illustrate important factors which affects the rate of photosynthesis: light intensity temperature carbon dioxide. The factors that affect the rate of weathering are humidity, the composition of rocks, high temperatures, vegetation and wind in a hot and wet environment, weathering tends to be rapid in dry climates, weathering is slower. O the objective of the experiment was to determine if different factors affect the reaction rate of alka-seltzer alka-seltzer provides fast relief to acid indigestion, upset stomach, heartburn, headaches, body aches and pains. In this experiment you will attempt to determine to obtain an accurate melting point you must heat the oil at a rate of 1 to 2 do not try to cool down a hot.

Also, your heart rate should stay in the lower ranges during warm-up and cool-down periods using a heart rate monitor is an easy way to keep track of your heart rate while you're exercising, or you can take your pulse (see below. Homers pizza is advertising the following deal:3 pizzas, up to 4 toppings each, 10 toppings to choose from 3 soft drinks, 5 varieties to choose from total cost $2499 the pizza toppings must be unique double, triple, or quadruple toppings are not allowed. What factors affect the rate of cellular respiration in multicellular determine the rate of cellular respiration, one could measure any of the following.
