the pin fell because of the heat supplied to the iron rod makes the wax to melt at one end the wax closer to the flame melted first the activity clearly shows that the heat moves from one end of the iron rod to the other this property of a material is known as a conductivity of a heat all metals conduct heat all metals donot have equal conductivity iron,copper and aluminium cooking vessels are preferred due to their high heat conductivity
