Identify two factors that can affect conductivity: 1 - Leaving Cert Home Economics - Question a - 2019

Temperature: The conductivity of most materials increases with temperature. For instance, in metals, as the temperature rises, more electrons gain energy and become free to conduct electricity. Conversely, for electrolytes, increasing temperature can enhance the movement of ions, thereby improving conductivity.

Concentration of Ions: In electrolytes, the concentration of ions directly affects conductivity. A higher concentration of ions leads to more charge carriers in the solution, thus increasing the overall conductivity. Conversely, a dilute solution will have fewer ions available to carry the charge, resulting in lower conductivity.
