Question

Q 2 What do you understand by conductivity of heat and electricity of a metal?​

Answer 1

Conductivity in metal is a measure of a material's ability to transmit heat, or electricity (or sound). The reciprocal of conductivity is resistance, or the ability to reduce the flow of those.

Answer 2

☞ Thermal conductivity or Conductivity of heat can be defined as the rate at which heat is transferred by conduction through a unit cross-section area of a material, when a temperature gradient exits perpendicular to the area.

☞ Electric Conductivity is the conductivity is the capacity to let the electric current flow.
