The temperature gradient across a copper rod of thickness 0.02m, maintained at two temperature junctions of 20°C and 80°C respectively is
3.0 x 102Km-1
3.0 x 103Km-1
5.0 x 103Km-1
3.0 x 104Km-1
Correct answer is B
Temperature Gradient = Δtemp.thickness
= 80−200.02
= 600.02
= 3000Km-1
= 3.0 x 103Km-1
