rate on different surface areas‚ depending on different types of water solution An investigation showing the effect of surface area on osmosis rate‚ including some different types of water concentration. Osmosis is a type of passive (not requiring energy) transport of water molecules across partially permeable membrane‚ from an area of high water concentration into area of low water concentration. But how does surface area affect rate of osmosis? Surface area plays important role in osmosis

least have to pick r and h such that pi r^2 h = 355. That means h = 355 / (pi r^2). The surface area of a cylinder is the top (pi r^2) plus the bottom (also pi r^2) times the lateral side (2 pi r h). So the total surface area is 2 pi r^2 + 2 pi r^2 + 2pi r h‚ or 4 pi r^2 + 2 pi r h. Substitute h = 355 / (pi r^2) into this to get the surface area in terms of just r. Now that you have the surface area in terms of just r‚ you can find the value of r that minimizes this by taking the derivative‚ stetting

red pigment from a beetroot cell and the surface area. To do this successfully I will need to alter the surface area of the beetroot cells accurately and then measure if any and how much dye is let out. I can hopefully then look at my results and then find a relationship between the two factors and be able to explain exactly why any changes took place. PREDICTION For this experiment I would expect the leakage of dye to increase as the surface area increases and this is based on the knowledge of

investigate the effect of the surface area to volume ratio on the rate evaporation of water in different sized containers. By measuring the time it takes for the whole amount of water to evaporate‚ a conclusion can be made about the validity of the surface to volume ratio in regards to the biological process of diffusion. Research Question: What is the effect of the surface area to volume ratio on the evaporation of water? Variables: - Independent: o Surface area in cm2 of the top most surface of

=1; for a non-spherical particle‚ the sphericity is defined as Dp: equivalent diameter of particle Sp: surface area of one particle vp: volume of one particle The equivalent diameter is sometimes defined as the diameter of a sphere of equal volume. For fine particles‚ Dp is usually taken to be the nominal size based on screen analysis or microscopic analysis. The surface area is found from adsorption measurements or from the pressure drop in a bed of particles. For many crushed materials

Sociology Dr.C.Barry McClinchey Residential Schools in Canada Before the nineteenth century‚ the Aboriginal people had their own way of teaching the children in their community‚ through organic education. In addition to providing knowledge and skills‚ organic education kept their culture alive (Ravelli & Webber‚ 2013: pg. 237). This is because the Aboriginal children would also be taught about their culture and its customs. But the Europeans thought‚ “Canada’s First Nation peoples were in
