Background Information Surface area will increase the speed of reaction as the greater the surface of the solid reactants‚ the more particles are required to expose and ‘cover’ the capacity of the solid. Increased surface area results in an increased chance of collisions between reactant particles. Since the collisions become more frequent and abundant‚ the rate of reaction increases. Aim The aim of the experiment is to see if a greater surface area of a dissolvable tablet creates a faster or

What similarities do the earth‚ an island‚ and a life raft possess? All the objects in some aspect are 3 different isolated environments. The earth is isolated in space with no life in reachable means. An island is isolated from the mainland‚ and the life raft is isolated from any land at all. All three are isolated. All three rely on their resources. All of earths life is reliant on the sun‚ water‚ ecosystems‚ etc. The island is a scaled down version of the earth with the same necessities. The life

eukaryotic and prokaryotic. Prokaryotic cells are usually unicellular‚ while eukaryotic cells can either exist as a single celled organism or be found in multicellular organisms. The unicellular and multicellular organisms are linked to cell size and surface area to volume ratio. The experiment for cell size and diffusion was set to see how and how much water can go to the cells. This movement of water is called Osmosis. Osmosis is the movement of water molecules from an area of low concentration (lots
