Answer:

There is an increase in both the average kinetic energy and the distance between the lead atoms.

Step-by-step explanation:

Hello,

Melting is a process in which due to the increase in the temperature a solid, in this case lead, turns out into a liquid. It means that its molecular arrangement is modified by cause of the transferred energy, in such a way, an increase in the average kinetic energy is attained due to the temperature increasing as long as the particles start to move faster to allow them to separate from their characteristic closeness in solids. In addition, as the particles separate, the distance between the atoms becomes progressively longer as the unshaped liquid is being formed.

Best regards.
