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:

The effect of size on the effectiveness of diffusion Aim: To use agar blocks infused with 0.1 Molar sodium hydroxide (NaOH) and phenolphthalein to investigate the relationship between shape and surface area: volume ratio on the effectiveness of diffusion. Hypothesis: That for a cube of agar‚ the time taken for complete colourisation due to diffusion of HCl is directly proportional to the cubes volume. Materials: |A block of agar (10cm x 5cm x 3cm) with 0.1M NaOH and |1x 250mL

the ideas of cultural diffusion. Cultural diffusion is the exchanging and adaptation of ideas amongst people of the world. It is a constant force that allows us to accept and modify an idea to mold into our own world. Throughout great civilizations of history‚ the idea of cultural diffusion has spread and continues to spread in present time. This idea usually enforces contact between neighboring strangers. McNeill addresses the specific issue of how cultural diffusion came to shape new civilizations

Fiber Optic Connector Assembly Oven-Cured Epoxy Application and Connector Assembly: 1. Set the curing oven to the temperature recommended by the epoxy manufacturer. 2. Follow manufacturer’s instructions for mixing the epoxy. 3. Secure needle to the syringe and load the syringe with epoxy while ensuring it is free of air pockets. 4. Insert the needle tip into the back of the connector until it bottoms out against the ferrule. Maintain pressure and slowly inject epoxy until a bead appears on the end

property k is dependent on the substances atomic structure & temperature‚ which will be verified in this experiment. The governing law of conduction‚ known as Fourier’s Law of Heat Conduction is represented by the equation: [4] Qcond= -kAcdTdx (1) Qcond represents the rate of heat conduction; Ac represents the cross-sectional area that the heat is being transferred through; k represents the thermal conductivity of the material; dTdx represents the approximation for temperature gradient across
