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