What is the difference between thermal and electric conductivity?
Wiki User
∙ 6y ago
Electrical conductivity is flow of electrons between two different points having different electric potentials.
Thermal conductivity is flow of electrons between two different points having different temperatures.
Electrical Conductivity in solids, is purely based on number of free electrons (number of free electrons and holes in semiconductors). But thermal conductivity is based on number of free electrons and also phonons.
Electrical conductivity in liquids and gases is also depends on number of free electrons but thermal conductivity in liquids and gases is because of molecular collision.

Conduction is the transfer of heat by contact between objects. Convection is the transfer of heat via fluids (liquids or gases), usually air.

Do elements that have high electric conductivity also have high thermal conductivity?
Usually it is, but exceptional case is of Graphite which has low thermal conductivity.
What is the thermal conductivity difference between cast aluminum and sheet plate aluminum?
I don't have a numeric answer for you, however, I do know that sheet aluminum has better thermal conductivity than cast. It has to do with the way that cast aluminum cools.
Are all metalloids semiconductors?
