Question

What is conductors and insulators ? Why solid conduct heat better than liquids and gases?

Answer 1

conductors are materials that transfer thermal energy easily. Thermal insulators are materials that do not transfer thermal energy easily.
The moving particles of a warm soild material can increase the heat energy of the particles in a cooler solid material by transferring it directly from one particle to the next. Since particles are closer together, solids conduct heat better than liquids or gases. Conduction moves heat through a material.
