Answer to Question #2506 in Molecular Physics | Thermodynamics for sana
How do concrete walls reduce the transmission of heat between the inside and outside of the building?
Concrete is porous, so it has a lower thermal conductivity than materials with smaller pores, such asš stone. Low thermal conductivity means that for example the house would be heated less through the walls if they are of concrete than in the case of stone. We can say that concrete decreases heat transmission between the house and the environment.
