Title: Surface Area vs. Rate of Reaction Research question: How can different temperatures affect the rate of reaction‚ when the reactant is in powder form? Hypothesis: If the temperature of the water is increased‚ the rate of reaction will also increase as the heat given off to the particles will increase leading to more movement and frequent collisions. Background information: Chemical reactions occur when two or more molecules interact with each other‚ but that can only occur when they

on top of the shorter cup to prevent any heat loss to the air. Then the shorter cup was secured on a base with tape and a hole was drilled with a stir stick on the top of the taller cup to allow the stir stick and a thermometer reach the chemical reaction. With the calorimeter set up and ready‚ the experiment was ready to be conducted. The calorimeter was placed on a metric scale and tared. Then 2.5g of a substrate was measured out using a small scoop and placed in the calorimeter. A scale was used

Compare and Contrast two theories of Personality Our personality is our characteristic pattern of thinking‚ feeling and acting (Psychology David G Myers)‚ it’s the combination of traits that ‘outlines the doctrine of uniqueness’ (Gifts Differing – Understanding Personality Types) that sets us apart from everyone else. Psychologists vary between themselves concerning the meaning of personality. Most would agree that it originated from the Latin word persona’ – meaning a theoretical mask – but they
