Kinetic Theory and Conduction
In solids the particles have strong forces of attraction which hold them closely together in a fixed, regular arrangement. They don't have much energy so can only vibrate about their fixed positions.
Liquids have weaker forces of attraction between the particles. They are close together but can move past each other. They have more energy and move in random directions at a low speed.
There are hardly any forces of attraction between the particles in a gas. They…
