Aim:To determine the relationship between Surface Area and Volume Ratio of a phenolphthalein impregnated agar block, and the rate of diffusion into the block. Description:Diffusion is the passive movement of particles from high concentration to low concentration. It is a very slow process so therefore the smaller the cell it is more efficient and faster. Hypothesis:As the volume of the agar block decreases, the rate of diffusion will increase because the speed of the molecules movement is directly associated to the volume. Responding Variable RV : rate of diffusion and percentage of diffusion. Constant Variable CV : time, stopwatch, ruler, same bottle of.

Mathematical methods have a wide scope in almost every field, be it Economics, Physics, Geography , or any other. Detailed knowledge and correct usage of Surface Area and Volume are important to excel and achieve perfection. Both concepts become significant while solving real-life problems relating to measurements and are studied under the Mensuration unit. Methods of Integration find applications in the calculation of Area and Volume of irregular and complex surfaces. Surface Area is the total area covered by the surface.
How Does the Surface Area to Volume Ratio Affect Heat Loss in Organisms?
To this 4 ml of 0. Exactly after seconds of adding H2O2, a set of 1ml of reaction mixture from the above was taken and 2 ml dichromate acetic acid was added. It was then kept in a boiling water bath for 10 minutes. All the tubes were then cooled under running tap water and finally readings were taken at nm against reagent blank.
They affect how rapidly Criteria: Criterion Analysis 6 Level Comments Evaluation 6 Communication 4 The Task: To determine how the surface area to volume ratio affects the rate of diffusion of sodium hydroxide through phenolphthalein infused agar blocks. Authenticity Declaration
