The unit of thermal conductivity is:

1.	The unit of thermal conductivity is:
Answer» `W m^(-1) K^(-1)` `J mK^(-1)` `J m^(-1) K^(-1)` `W mK^(-1)` SOLUTION :`(d Q)/(dt) = kA (dT)/(dx)` `:. K= ((dQ)/(dt))/(A xx (dT)/(dx))` `:.` Unit of k `= (""_(J)//""_(S))/(m^(2) xx ("kelvin")/(m))` `= (W)/(m xx "kelvin")` `=W m^(-1) K^(-1)`
