Answer

i. As, the iron sphere goes deeper in the wax layer, the specific heat capacity of the iron is maximum.
ii. As, the lead sphere does not reach much of the depth in wax layer, the specific heat capacity of lead is minimum.
iii. The amount of heat energy required to raise the temperature of a unit mass of an object by $1^{\circ} C$ is called the specific heat or specific heat capacity of that object.
