Heat Conductors and Insulators

Heat conduction is a process of transfer the heat energy through materials by collision and diffusion of particles. This is due to the temperature gradient. The material which conducts the heat energy is known as heat conductors or thermal conductors. Some materials are not conduct the heat which is termed as heat insulators or thermal insulators. The details about these materials are given in the following section.

Thermal Conductors and Insulators

Back to Top
From the above paragraph, it is clear that thermal conduction is occur when there is a temperature gradient is present. The energy transfer is taking place with in the material, there is no movement in the whole material itself. Thermal conduction can occur in all states of matter such as solids, liquids, gases and plasmas. When two bodies are in contact with each other, spontaneous heat flow will start from higher temperature region to lower temperature region. Some of the thermal conductors are listed below:
  • Copper
  • Gold
  • Steel
  • Water
  • Aluminium

Thermal insulators are nothing but the material which does not conduct  the heat energy. The insulating material have the strong molecular bond. The process is known as the insulation. It controls the heat transfer from one region to another. In the case of thermal insulators, the heat transfer process like conduction, convection and radiation are not taking place. Some of the examples of thermal insulators are given below.

  • Non metals
  • Rubber
  • Wood
  • Plastics
  • Cloth
