Is air a good insulator? Plan In this experiment I am trying to find out if air is a good insulator. There are three different types of heat transfer Conduction, Convection and Radiation. Conduction mostly occurs in metals because as metals get hotter the ions in it start to vibrate and they get a lot more kinetic (movement) energy. Then this energy is transferred to the cooler parts of the metal where it has free electrons as they diffuse through the metal, bumping into other ions and electrons. Metals are really good conductors because they allow energy through them quickly on the other hand non-metals are not good conductors because they let energy through them slowly but that makes them a good insulator. Convection only occurs in liquids and gasses. As a liquid or gas gets hotter and hotter the particles move faster causing it to expand and becomes less dense then other regions. Once...
