P1a 1.1 Thermal Radiation * Thermal or heat radiation is the transfer of energy by infra-red waves. * Thermal radiation is energy transfer by electromagnetic waves. * All objects emit thermal radiation. * The hotter an object‚ the more thermal radiation it emits. * Heat radiation can travel through a vacuum. 1.2 Surfaces and Radiation * Dark‚ matt surfaces are better emitters of thermal radiation than light‚ shiny surfaces. * Dark‚ matt surfaces

Science Fair Project Ideas — Insulation Testing This is one of the more practical science fair project ideas since it relates to insulation‚ which is a common material in home construction. I tested the insulation value of some common materials to see which one worked best. The pictures below show pictures of the basic set up I used. The figure below shows three large

While it is less brittle than many other ceramics‚ it lacks impact resistance; Space Shuttle Columbia was destroyed during atmospheric reentry after one of its RCC panels was broken by the impact of a piece of foam insulation from the Space Shuttle External Tank. This catastrophic failure was due in part to original shuttle

Theory Project 1 Natural and Manufactured fibres by- Ama Bona Owusu 12MC What are natural fibers? Natural fibers are any hair like raw material that can be directly accessible from an animal‚ vegetable‚ or mineral source (plants) and an be changed into non-woven fabrics such as felt or paper or‚a woven cloth when it has been span into yarns. When natural fibers can be discussed further and can be refereed to as agglomeration of cells in which the diameter is negligible in

carrying ability of the structure. The interconnection of the walls and roof together with the foundation makes the structure a monolith unit. The overall thickness of the wall ranges from 45-60cm. the thick and heavy walls give way for a very good thermal insulation and help maintaining a constant temperature within by providing a high time lag which is usually greater than 8 hours. For the two bottommost layers single wooden logs while for the upper layers double wooden logs are used. The open spaces (height

disaster occurred minutes before Columbia was scheduled to land at Florida’s Kennedy Space Center. An investigation later determined the catastrophe was caused by a problem that took place shortly after launch on January 16‚ when a piece of foam insulation broke off from the shuttle’s propellant tank and damaged the edge of the shuttle’s left wing. The Columbia disaster was the second major tragedy in the history of the space shuttle program after the space shuttle Challenger broke apart shortly after
