Question

write an expression for the heat conducted through a metallic rod and hence define the coefficient of thermal conductivity and give its si unit and dimensions​

Answer 1

Answer:

The for the coefficient of thermal conductivity is

Kth=AΔTtQΔx

Dimensional formula of Kth

[Kth]=[Area].[Temperature].[time][Heat].[length]

[Kth]=[L2].[K].[T][ML2T−2].[L]

[Kth]=[MLT−3K−1]
