GROUP 4 PROJECT PHYSICS REPORT NAME: ZHUANG YUAN CLASS: 5.08KINGS Background information We have read some article on the internet regarding the 'relationship between electrical conductivity and ions present'. Here is some abstract from the internet article: '......however the difference in times of occurrence of the maxima of the polar conductivity and various ions concentrations indicate that all ions of different categories may contribute to polar conductivity in varying degrees'(source from the internet www.agn.org/pubs/crossref/1992/92JD01915.shtml ) hence our project is aimed at relating the ions present with the environment using a physics approach. Purpose To find the conductivity of pond water and its relationship with the presence of ion. Hypothesis The higher the potential difference of the pond water the more ions present. Variable DEPENDANT INDEPENDENT CONTROLLED The potential difference of pond water Pond water from different parts of Singapore Volume of sampled water used Resistivity of wires used (in multi-meter) Equipment and apparatus 1)Multimeter 8) Water samples from different parts of...
