Two rods one of copper and the other of mild steel, both of diameter 20 mm and length 250 mm are coated with a uniform layer of wax all around. These rods are placed vertically in a boiling water bath with 200 mm, length of each rod projecting outside. If the melting point of wax is 10?C, then
[A].
equal quantity of wax will meet on the two rods
[B].
more wax will melt on copper rod as compared to mild steel rod
[C].
more wax will melt on mild steel rod as compared to copper rod
[D].
nothing can be predioted as the data is insufficient
