Permeable Membrane Semi Permeable
856 wordsStudying the Effect of Various Glucose Concentrations on Osmosis in a Potato Osmosis is the process in which water particles move from an area of high water concentration to an area of low water concentration through a semi-permeable membrane until the concentrations are equal. Osmosis has the same basic theory as diffusion. Particles are moving from an area where they are in great concentration to an area where they are in low concentration until the concentrations are the same. Osmosis is this...

Rate Of Reaction Bunsen Burner
2,301 wordsFor this investigation I am going to investigate the effect of the concentration of an enzyme, in this case Amylase, on the time taken for the enzyme to fully breakdown the substrate, which in this case is starch. The reason why these two enzymes have to be used is because each enzyme is designed specifically to break down only one substrate as each enzyme is made of a protein that causes it to be a specific shape, in this case the enzyme Amylase can only break down starch to dextrin. I am going...

Factors Affecting 10 Cm
1,336 words'Planning Osmosis is the net movement of water molecules from a region of their higher concentration through a partially permeable membrane. This movement usually takes place through a membrane which is permeable to water but not to solutes. In my investigation I am going to be investigate the factors affecting the rate of Osmosis. Some factors affecting this are: Length? of membrane Temperature? of water Concentration? of solution The factor I am going to investigate is the length. Equipment Vi...

1,665 wordsInvestigating The Factors Which Affect The Resistance Investigating The Factors Which Affect The Resistance Of A Wire Background KnowledgeRESISTANCEElectrons move more easily through some conductors when a potential difference is applied. Resistance is determined by how good or bad a conductor a material is. A good conductor has a low resistance while a poor conductor has a high resistance. THE OHM Resistance is defined by: R = V/I? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?...

Rate Of Reaction Calcium Carbonate
2,367 wordsInvestigation Into The Relationship Between Temperature Of Investigation Into The Relationship Between Temperature Of Acid And The Rate Of Reaction In The Reaction Of Caco 3 And Hcl Background Information The speed at which reactants are converted into products during a reaction is referred to as its rate. Usually in a reaction, the amount of the product of the reaction is measured to work out the rate of the reaction. In this reaction, the rate will be calculated by the equation: Rate = 1 Time....
