Many landfills were filled by these non-biodegradables that can last forever. This group focuses on polystyrene since people are having difficulty in recycling this material. The properties of polystyrene that make it a useful material – light weight‚ low cost‚ and durable‚ make it also hard to recycle. Procedures Used: The

the heat greatly. I have found information from the internet‚ that the polystyrene will be the best in insulator. I will have to bung up the end of the test tube as well because heat will be lost by convection currents. By keeping the test tubes well insulator the water molecules should be zooming around in the water at the same speed for a longer time with all that trapped heat energy. Prediction I predict that polystyrene will be the best insulator against all the others. I think though it will

Chapter II Review of Related Literature and Studies Related Literature Polystyrene Commonly known as ’Styrofoam’ that is one of the most widely used type of plastics. It is a strong plastic created from erethylene and benzine that can be injected‚ extruded‚ or blow molded; making it a very useful and versatile manufacturing material. It is also a rigid‚ transparent thermoplastic‚ which is present in solid or glassy state at normal temperature. But‚ when heated above its glass transition temperature
