The Investigation Report-Chemistry By Sinthiya Punnialingam 9B 1.Planning Problem: What speeds up the dissolving process? Hypothesis: I think these factors will affect the dissolving process: * Temperature at which the reaction is carried out. * Particle size of the solute. * Stirring of the solution. However in my investigation, I am investigating temperature and the particle size of the solute. Prediction From using my scientific knowledge and understanding, if the particle size of the solute is smaller, the particles can easily diffuse with the solvent's particles and fill in the spaces between them. In addition, the surface area is also increased if the particle size of the solute is smaller, giving a greater area for the particles of the solvent to collide with, so the solute can dissolve quickly. If the temperature is high, more kinetic energy is given to the particles, therefore the particles would move faster, mix in with the particles of the solvent, and...
