The Rate of Diffusion in Different Temperatures Purpose: To see if the temperature of a solution will change the rate blue diffuses in it. This will be tested by timing how long it takes dye to diffuse in warm water‚ cold water‚ and room temperature water. Hypothesis: I think that the dye will diffuse at a faster rate in the warm water than in the cold water. I believe that the room temperature water will have the dye diffuse faster than the cold water but slower than the warm water. Variable:

Biology diffusion Science ISA To find out if concentration affects the rate of diffusion. I predict that the higher the concentration of acid the faster the reaction will be. Dependent variable: We are measuring the time taken for the pink indicator to turn clear when hydrochloric acid is added to it. Independent variable: We are changing the molar of hydrochloric acid we are adding to the gelatine cubes. Apparatus: * 1 measuring cylinder * 1 test tube * 1 stop clock * A large gelatine

The Role of Surface Engineering in the Automotive Industry The subject of surface engineering in the automotive industry has developed significantly in the last decade. A large driving force for the need for surface treatments has been energy consumption. 30 per cent of all energy consumed in the European Union derives from transportation activities‚ relying solely on fossil fuels. Due to this‚ and the push to reduce the emissions of polluting gases‚ car manufacturers must produce increasingly

1. Diffusion and Osmosis‚ June 4‚ 2013 2. Purpose: The purpose of this lab is to help give visual understanding of diffusion which is a solution of high concentration spontaneously (no energy required) moving to an area of low concentration. Also taking a look at osmosis‚ which is the movement of chemicals across the cell membrane. Osmosis requires some type of energy to be put in for this to happen. After these experiments we should have a better idea and visualization of how chemicals transfer

Lab # 2 Diffusion & Osmosis Introduction Kinetic energy‚ a root of energy stored in cells‚ causes molecules to hit into each other and move in new directions. Diffusion is the result of this contact. Diffusion is the random movement of molecules to an area of lower concentration from an area of higher concentration. Osmosis is a type of diffusion. This is the diffusion of water through a selectively permeable membrane from a region of higher water potential to a region of lower water
