Physics Why two thin shirts can keep us warmer than a single thick shirt in winter ? No radiation of heat takes place Two thin shirts become thicker so prevent transmission of heat Air layer between two shirts works as good conductor Air layer between two shirts behaves like insulating media No radiation of heat takes place Two thin shirts become thicker so prevent transmission of heat Air layer between two shirts works as good conductor Air layer between two shirts behaves like insulating media ANSWER DOWNLOAD EXAMIANS APP
