## Heat Conduction

Heat conduction ( $$COND$$ ) (one of three ways to heat transfer: conduction, convection and radiation) is the flow of heat between two objects having different temperatures that are in contact with each other.

### Heat Conduction Formula

$$Q = \frac { kA \Delta T t } {d}$$

$$Q = \frac { kA \left( T_h \;-\; T_c \right) t } {d}$$

Where:

$$Q$$ = heat conduction or transfer

$$k$$ = thermal conductivity

$$A$$ = cross sectional area

$$\Delta T$$ = temperature differential

$$T_h$$ = higher temperature

$$T_c$$ = cooler temperature

$$t$$ = time taken

$$d$$ = thickness of the material
