Hawthorne Experiment. Advantages: During the experiment the performance of the group has increased (Not because of improving conditions‚ but because of the communication and collaboration) Disadvantages: there were personnel changes‚ that is the workers hostile watching the situation changed for those who would like to work in such conditions (that is attended only those workers who are more willing‚ not all workers) Conclusion: This experiment showed that workers are willing to actively

to determine the solubility constant of calcium hydroxide. But‚ there are few limitations in solubility constant concept‚ like the Diverse Ion effect and the Common ion effect. Sources of error probably were the assumptions made throughout the experiment and can be explained further by the limitations of the solubility constant. ------------------------------------------------- ------------------------------------------------- Introduction In a reaction where a slightly soluble ionic solid

Describe the physiological approach to the study of the mind. Explain how Donders experiment can be repeated in a modern laboratory using the physiological approach to the study of the mind Donder’s work attempts to describe the processes going on in the mind‚ by analyzing cognitive activity into separate stages. Until Donder’s work‚ many scientists had assumed that the mental operations involved in responding to a stimulus occurred instantaneously. Donder was particularly interested in "timing

Experiment 5: Shifting Equilibrium A solution is in equilibrium when the rate of forward reaction and the rate of reverse reaction are equal. This equilibrium may be disturbed when the concentration of the reactants‚ the concentration of the products or the temperature is changed. If the process involves gases‚ a change in pressure can also affect the position of equilibrium. The concept behind this is Le Chatelier ’s Principle which states that when a system is disturbed through application

Title : The movement of substances across a semi permeable membrane Objective : To study the movement of substances across a semi permeable membrane Problem statement : What factor influences the diffusion of substances through a semi permeable membrane? Hypothesis : The diffusion of molecules across a semi permeable membrane is based on the size of the molecule Variables: a) Manipulated : Size of solute molecules b) Responding : Colour of solution c) Fixed : Temperature and time

5.05 Mixtures and solutions Lab report Ink Chromatography Chromatography is also used to compare and describe chemical substances. The chromatographic sequence of sorbed substances is related to their atomic and molecular structures. A change in a chemical substance produced by a chemical or biological reaction often alters the solubility and migration rate. With this knowledge‚ alterations or changes can be detected in the substance. Chromatography serves mainly as a tool for the examination and
