Surface Area to Volume Ratio and the Relation to the Rate...
Surface Area to Volume Ratio and the Relation to the Rate of Diffusion Aim and Background This is an experiment to examine how the Surface Area / Volume Ratio affects the rate of diffusion and how this relates to the size and shape of living organisms. The surface area to volume ratio in living organisms is very important. Nutrients and oxygen need to diffuse through the cell membrane and into the cells. Most cells are no longer than 1mm in diameter because small cells enable nutrients and oxygen to diffuse into the cell quickly and allow waste to diffuse out of the cell quickly. If the cells were any bigger than this then it would take too long for the nutrients and oxygen to diffuse into the cell so the cell would probably notâ⬠¦show more contentâ⬠¦The larger blocks have a smaller surface area than the smaller blocks. The smallest block has 1.2mm squared of surface area for every 1mm cubed of volume. The largest block only has 0.2mm squared of surface area for each 1mm cubed of volume. This means that the hydrochloric acid is able to diffuse the smallest block much faster than the largest block. When the Surface Area/Volume Ratio goes down it takes longer for theShow MoreRelatedSurface Area Volume Ratio Experiment1104 Words à |à 5 PagesSurface area / Volume ratio Experiment Introduction: The surface area to volume ratio in living organisms is very important.

BACKGROUND THEORY / INTRODUCTION Cells are the basic unit of life of which all living organisms are built upon, they are the smallest living organizational unit and they all come from pre-existing cells which has been supported by several scientists in the formation of cell theory [Biological physics, 2013]. The structure of a cell is strongly correlated with its function and the way it acts in relation to other cells andRead MoreOsmosis And Diffusion Lab : Experiment2755 Words à |à 12 Pages Osmosis and Diffusion Lab Saagar Chitale 10/13/14 AP Bio Pd.5 Introduction: The first part of this three part lab was an investigation that examined the relationship between rate of diffusion and the surface area to volume ratio. To simulate this, we used an agar cube with NaOH and phenolphthalein mixed in, and dropped it in an HCl solution. As the HCL diffused in and reacted with the phenolphthalein, we were visually able to see diffusion at work. Diffusion is the movement of moleculesRead MoreGas Exchange : A Important Bodily Process3474 Words à |à 14 Pagesis that they need oxygen, and do not need carbon dioxide. Oxygen is taken in by the organism, and carbon dioxide is released by the organism. Diffusion plays a big role in the process of gas exchange. In this context, diffusion is a movement of a gas from an area of a high concentration to a low concentration, until an equilibrium is reached. Diffusion allows an organism to obtain oxygen necessary for cells in order to stay alive. This in turn, can be affected by environmental factors such as temperatureRead MoreWhy Gas Exchange Is Essential For All Organisms2297 Words à |à 10 Pages The carbon dioxide is a waste product of respiration so it is diffused out of the organismââ¬â¢s body. All Gas exchange mechanisms must be; moist as gases need to dissolve in H2O to diffuse across a membrane. Have a large surface area which is related to requirements (metabolic rate activity/lifestyle) of an organism, thin enough membranes for gases to diffuse across. Gas Exchange in Mammals Gas exchange occurs in land mammals by the air entering through nose or mouth. The nasal cavity is a structuralRead MoreDesign Of An Integrated Circuit9821 Words à |à 40 Pagesintegrated circuits and the lead frame (wire bonding) has been increasingly affected by phenomena such as Joule heating and electromigration, which have accelerated a particular interface reaction in the wire-pad diffusion couple. Nonetheless, the performance of interface reaction in the wire-pad diffusion couple is also naturally affected by the materials used in the wire bond interconnection. 1.2 Au/Al system vs. Cu/Al system in wire bonding process In the past, the use of Au-wire and Al-pad was widely extendedRead MoreLab Report Gas Diffusion3047 Words à |à 13 PagesS5E1 Gaseous Diffusion 1.0 ABSTRACT In this experiment, our objective is to find out the gas diffusion coefficient, D of acetone in the air. This experiment is conducted at a temperature of 50à ºC and atmospheric pressure. The method that is applied to conduct this experiment is called the Winkleman method where the level of acetone (Z) is determined every 15 minutes by using a microscope. With the level of acetone being determined, a graph of t/L+Lo (min /mm) vs. L-Lo (mm) is plotted and theRead MoreThe explicit presentation of the mathematics involved in the Arrhenius equation (Michels, Tsong,3200 Words à |à 13 Pagesimplementation of the physical processes described in the mathematical equations into a model replicating the natural environment is a complicated problem hard to solve (Stevenson 1998).

Conduction Conduction is the transfer of heat by direct contact of particles of matter. The transfer of energy could be primarily by elastic impact as in fluids or by free electron diffusion as predominant in metals or phonon vibration as predominant in insulators. In other words, heat is transferred by conduction when adjacent atoms vibrate against one another, or as electrons move from atom to atom. Conduction is greater in solids
