Description

Thermal Conductivity of Materials

Different materials have varying abilities to conduct thermal energy. Metals are known for their high thermal conductivity, while materials like wood and plastic are known for their insulating properties. Some materials, such as ceramics, fall in between these two categories.

  1. a
