What is conductivity? On what factors does conductivity depend?

(N/A) Conductivity $(k)$,also known as specific conductance,is the reciprocal of resistivity $(\rho)$.
Mathematically,$k = \frac{1}{\rho}$.
Conductivity depends on the following factors:
$1$. Nature of the material: It depends on the nature of the electrolyte and the solvent.
$2$. Concentration of ions: It depends on the concentration of ions present in the solution.
$3$. Temperature: It increases with an increase in temperature because the kinetic energy of ions increases,leading to higher mobility.
