# Heat Conduction

Heat conduction (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.

- Abbreviated as
**COND**

## 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
