gain resistance to nickel and aluminium over generations. It discusses the importance of bacteria and how it is used throughout everyday life. It discusses that some bacteria is used for human applications and shows how it can be helpful in certain situations. This report will discuss the background information on E.coli K12 and the uses of bacteria. Throughout the investigation a series of experiments will be conducted to determine if metals such as nickel and aluminium have a resistance to E.coli

Carbon fibre reinforced polymer Name Institutional analysis Introduction Carbon Fibre reinforced polymer commonly known as CFRP is a very strong composite material that is majorly preferred for many automotive and aeronautical application due to the fact that despite their strength that still light that the traditional metallic materials. The polymers often used to make this composite material is epoxy‚ polyester‚ vinyl and even nylon. Thus in making CFRP carbon fibre is often combined with polymers

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 a longer period of time. Materials

failure mode of buckling‚ by loading five slender aluminium elements in compression. Procedure In this experiment‚ we used a Digital Force Display (DFD)‚ to observe the failure mode of buckling‚ of five slender aluminium elements. We used de DFD to put load on the elements in compression‚ starting with the longest one‚ and kept putting on load until there were no further increase in the load. We repeated this for each of the five slender aluminium elements four times. Result STRUT NUMBER LENGTH (mm)

is also known as metallic sound. This is the cause that metal wires are used in making musical instruments. Conduction:- Metals are good conductor of heat and electricity. This is the cause that electric wires are made of metals like copper and aluminium. Malleability:- Metals are malleable. This means metals can be beaten into thin sheet. Because of this property iron is used in making big ships. Ductility:- Metals are ductile. This means metals can be drawn into thin wire. Because of this property

The density of the iron cube would be greater than the density of the aluminium cube. One explanation from that is that the particles/molecules in the iron cube are more tightly packed than the particles in the aluminium cube The density of a particular substances is always the same‚ no

DEFINITIONS OF OXIDATION AND REDUCTION (REDOX) This page looks at the various definitions of oxidation and reduction (redox) in terms of the transfer of oxygen‚ hydrogen and electrons. It also explains the terms oxidising agent and reducing agent. Oxidation and reduction in terms of oxygen transfer Definitions • Oxidation is gain of oxygen. • Reduction is loss of oxygen. For example‚ in the extraction of iron from its ore: [pic] Because both reduction and oxidation are going on side-by-side
