Introduction
Investigation: Insulation
Introduction
This practical investigation involves investigating what kinds of materials are best at keeping water in a beaker warm. A material that prevents this heat loss is called an insulator. Insulators have to prevent three types of heat loss:
· Conduction
· Convection
· Radiation
Conduction of heat occurs mainly in solids. This process is where vibrating particles pass their extra vibration energy to neighbouring particles.

Conclusion
2. The other materials seem more solid and protective to the heat.
The best insulator out of the whole lot will probably be polystyrene. I chose this for my best insulator because:
1. All non-metals are good insulators
2. Polystyrene it often used to insulate hot and cold drinks. There are no gaps for the heat to escape.
I predict that these factors will effect the efficiency of the material.
