Plan - Investigating what kinds of materials are best at keeping water in a beaker warm

Extracts from this document...

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.

Middle

Radiation of heat can also be called infer-red radiation. Heat radiation can travel through a vacuum. This process is different from the other two it travels in straight lines and at the speed of light. This is the only way heat can reach us from the sun. Heat radiation travels through transparent media like air, glass, and water. No particles are involved

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.

  1. Thermal Insulation

    This is why we can still feel the heat of the sun although it is 150 million km away from the Earth. Where is thermal insulation used? If you have an object or area that is at a certain temperature, you may want to prevent that material from becoming the same temperature as neighbouring materials.

    When the particles move faster the temperature tends to rise. When the temperature had risen the heat goes from a hot surrounding to a cooler surrounding. There are 3 main ways heat can travel by conduction, convection and radiation. Conduction Conduction occurs mainly in solids.
