What happends to the particals of a soild as it melts?

Answer 1

The particles in a solid are very tightly packed together and rigid. The particles in a liquid are less tightly packed together. When a solid like lead is heated, the particles spread out and can move more, making a liquid.

Answer 2

Essentially the Lead atoms will start to lose their bonding strength as the metallic bonds are slowly broken down. When enough of these metallic bonds break the Lead block will no longer have a rigid structure as its atoms cannot hold together and at that point they enter a liquid state as some of the bonds have managed to stay allowing the liquid Lead atoms to stay together and not seperate entirely and become a gas.

Answer 3

MELTING. When a solid is heated, the particles are given more energy and start to vibrate faster. At a certain temperature, the particles vibrate so much that their ordered structure breaks down. At this point the solid melts into liquid.
