# Heat Transfer by Conduction

Heat transfer by conduction ( \(Q_c\) ) (also called heat conduction, heat radiation, or heat transfer) is the flow of heat between two objects having different temperatures that are in contact with each other.

### Heat Transfer by Conduction Formula

(Eq. 1) \(\large{ Q_c = \frac { kA \Delta T t } {d} }\)

(Eq. 2) \(\large{ Q_c = \frac { kA \left( T_h \;-\; T_c \right) t } {d} }\)

Where:

\(\large{ Q_c }\) = heat transfer by conduction

\(\large{ A }\) = area cross section

\(\large{ T_c }\) = cooler temperature

\(\large{ T_h }\) = higher temperature

\(\large{ \Delta T }\) = temperature differential

\(\large{ t }\) = time taken

\(\large{ k }\) = thermal conductivity

\(\large{ d }\) = thickness of the material
