The liquid allows the solid to sink due to the form of the solid. Think of a steel ship form, when it is placed in water it displaces a certain amount of liquid and if the weight is more than the amount of displaced liquid then the ship would sink because the water would spill over the sides. The lead does the same thing.

As per the principle of Archmedes "any material will float on a liquid if the weight of the displaced liquid is more than the weight of the material.".In the present case we are putting solid lead into liquid molten lead, as the volume occupied by certain weight of lead in solid state is much less than the volume occupied by the same weight in liquid state,hence, the weight of molten lead displaced by solid lead will be less than the actual weight of the solid lead.Therefore, the piece of lead will sink in the liquid molten lead.

The solids have more density than the liquids. There are an exception: the solid ice is the surely only* solid that float in the molten ice (the water).
* I dont know if the ammonia gas/liquid system have the same condition

Solid lead is more dense than liquid lead. Lead, like almost all materials (water is an exception) expand as they warm past melting.

For the same reason that cold air sinks and hot air rises. Warmer molecules and atoms are more energetic, bang against each other, space themselves out more, and are therefore less dense and heavy by volume.
