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.

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.

    Conduction Conduction occurs mainly in solids. Thus is the process where vibrating particles pass on their extra vibration energy to the nearby particles. This process goes on through out the solid until it causes a rise in temperature at the other side. The heat that is usually transferred by conduction is very slow if convection can't

    A planting container and dirt were obtained. Each seed was planted about 1inch down into the dirt and 2 inches apart from each other. All seeds were planted categorically. Marking sticks were labeled with the type of seeds that were planted (0; 50,000; 150,000; 500,000; 4,000,000). The labels were placed next to the appropriate seed categories in the planting containers.
