In a hiring freeze, an employer decides to stop hiring employees for all non-essential positions. It allows an employer to consolidate current employees and potentially restructure departments to complete the work that is essential for serving the customers of the business.
Since the electrical conductivity is a measure to the capacity of water to conduct electrical current, it is directly related to the concentration of salts dissolved in water, and therefore to the Total Dissolved Solids (TDS). Salts dissolve into positively charged ions and negatively charged ions, which conduct electricity.
8. These days salinity is measured by measuring the electrical conductivity of a seawater sample. The conductivity is directly proportional to the content of dissolved salts and can be, therefore, parlayed into a salinity determination. 9. When seawater evaporates or is diluted by precipitation, only the proportion of H2O changes so the proportions of these salts are unchanged.
