        The unit of thermal conductance is

    A)  \[W{{K}^{-1}}\]                               

    B)  \[J{{K}^{-1}}\]

    C)  \[WK\]                                

    D)  \[JK\]

    Correct Answer: A

    Solution :

                    Thermal conductance\[=\frac{\Delta Q}{t\Delta \theta }\] \[=\frac{J}{sK}=\frac{J}{s}{{K}^{-1}}\] \[=W{{K}^{-1}}\]
