Investigation 4.2: Factors Affecting Viscosity Question How does changing the temperature (°C) of glycerin affect the viscosity s -1 of glycerin (l)‚ when tested by dropping a marble from a constant height into the glycerin (l) and timed with a stopwatch until the marble hits the bottom? Design Independent Variable: The independent variable of this experiment is the temperature (°C) of the glycerin (l). Dependent Variable: The dependent variable of this experiment is the viscosity s -1 of the glycerin

Biology Enzymes IA Design Introduction: Enzymes are globular proteins‚ they are responsible for most of the chemical activities of a living organism. They act as catalysts‚ substances that affects the reaction of other substances without being destroyed or altered during the process. They are extremely efficient in the body system of living organisms‚ one enzyme may catalyse over a thousand chemical reactions every second. But there are certain conditions that need to be fulfilled in order for the

Determining the equilibrium constant from pH values of changing concentrations of ethanoic acid Design Research question: How will altering the concentrations of ethanoic acid affect the pH value‚ and‚ in-turn‚ the equilibrium constant? Background information: When weak acids react‚ the reaction typically does not go to completion. Rather‚ the system goes to an intermediate state in which the rates of the forward and reverse reactions are equal. Such a system is said to be in chemical equilibrium
