Question

two similarities between heat conduction and electrical conduction​

Answer 1

The thermal conductivity of this metal is, like electrical conductivity, determined largely by the free electrons. ... Both thermal and electrical conductivity depend in the same way on not just the mean free path, but also on other properties such as electron mass and even the number of free electrons per unit volume.

Thermal conductivity is looking at the transmission of molecular vibrations through a material which are measured as temperature. ... Electrical conductivity is measured by the ability of atoms or molecules to transfer electrons from one to the next.
