The Effect of Different Types of Insulation on Heat Retention Aim I am going to investigate the effect of different types of material on heat retention. "Which of the four materials‚ cotton‚ foam‚ aluminium foil and bubble wrap‚ is the best insulator?" Hypothesis The four materials tested in this experiment are cotton‚ foam‚ aluminium foil‚ and bubble wrap. Materials that are good insulators will absorb heat slowly and therefore the water inside the cup will stay warm for

The Space Shuttle Columbia was the second space shuttle disaster and the first shuttle lost on land happened on February 1‚ 2003. In this mission‚ six American astronauts and Israel’s first spaceman died when the space shuttle Columbia disintegrated 200‚000ft above Texas. They are David Brown‚ Rick Husband‚ Laurel Clark‚ Kalpana Chawla‚ Michael Anderson‚ William McCool and Ilan Ramon. Rick husband is the Columbia’s commander was a US air force colonel recruited to the space program in 1994. He

Heat transfer is a discipline of thermal engineering that concerns the generation‚ use‚ conversion‚ and exchange of thermal energy and heat between physical systems. Heat transfer is classified into various mechanisms‚ such as thermal conduction‚ thermal convection‚ thermal radiation‚ and transfer of energy by phase changes. Engineers also consider the transfer of mass of differing chemical species‚ either cold or hot‚ to achieve heat transfer. While these mechanisms have distinct characteristics

Foam concrete advantages Foam Concrete is normal concrete with bubbles of air inside. Therefore it has the same characteristics with many additional advantages. CLC (foam concrete) blocks are used for building cottages‚ wall insulation in multistory buildings and internal partitions. Also CLC can be produced and poured for floors and roofs on-site. In roofs it can be used because of very good insulating and lightweight. For floors CLC offers faster installation and a less expensive option because

unique to any other known materials in the world. An aerogel is a synthetic porous ultra-light material derived from a gel‚ in which the liquid component of the gel has been replaced with a gas. The result is a solid with extremely low density and thermal conductivity. Nicknames include "frozen smoke"‚ "solid smoke"‚ "solid air" or "blue smoke" owing to its translucent nature and the way light scatters in the material; however‚ it feels like expanded polystyrene (Styrofoam) to the touch. Aerogel was
