//__Teflon __// __**WHAT IS TEFLON? **__ Teflon, also known as Polytetrafluoroethylene (PTFE) is a colourless, odourless white powder formed from a chemical reaction with a refrigerant gas called tetrafluoroethylene (TFE). The formula for Teflon is CF 2 and it's used to make pots/pans which make the pans smooth and slippery. It’s also known as non-stick. It has also made an impact on the industrial world that can be found in electronics, aeronautics, embedded in the fabrics of your clothes, used as thread seal tape for plumbing applications and much more.

__** HOW IS TEFLON MADE? **__

Teflon started out as a white powder by a refrigerant gas tetrafluoroethylene (TFE) undergoing a chemical reaction. A research chemist named Roy Plunkett had filled up TFE into a cylinder expecting to open it and have the gas still inside it, but when he and his lab assistant Jack Rebok opened the cylinder, they had discovered a white powder which had gone through a reaction called polymerization. PTFE is a long chain polymer by fluoride atoms, enclosing all of the carbon chains which means that it can’t react with other molecules making PTFE one of the most inert (non-reactive) substances in the world.

As mentioned before, Teflon is very inert which means that it’s highly not reactive. It also has a high melting point, a low dissipation factor and high surface resistivity . Also another property is the high voltage that the insulating material can withstand before it breaks down. PTFE mechanical properties are low compared to other plastics, but its properties remain at a useful temperature range of -73°C to 204°C.

__**IS TEFLON SAFE? **__ As stated before, Teflon is inert and it’s also non-toxic, but Teflon can start to break down at temperatures over 260 degrees ( °C) which can lead up to the release of toxic chemicals. These chemicals can be fatal to birds and may cause flu symptoms towards humans. Mainly, the health concerns around Teflon is about the production and not its use, therefore, teflon is safe to use.



__**CAN TEFLON CAUSE CA **____**NCE **____**<span style="font-family: 'Times New Roman',serif; font-size: 12pt;">R? **__ <span style="font-family: 'Times New Roman',Times,serif; font-size: 12pt;">Many people speculate if Teflon can cause cancer but the truth is that Teflon itself doesn’t but it’s a compound that’s used in the making of Teflon. The compound is called Perfluorooctanoic acid also known as PFOA. It can be potentially carcinogenic but The DuPont chemical company which Roy Plunkett was working with, are currently trying to find a substance that can replace PFOA. Scientific studies show that it’s more likely have PFOA is your carpets rather than your pots and pans.

First a pan is dipped into hydrochloric acid to cover up the whole pan so that the PTFE will hold on to it, then sprayed with a sticky substance that would make the PTFE stick to the surface of the pan, and finally the pan is completely sprayed with PTFE. After that procedure if finished, the pan is heated at 425°C to melt the PTFE and make sure that it sticks to the pan’s surface.

- Metallurgy is the study of the chemical and physical properties of a metal - Smelting is where an ore is heated with other chemicals at over 1000° C - Nonferrous metals, like copper and zinc, are produced from sulphide ores
 * Things I learned from Metallurgy are:**

- Iodine is a dark gray/purple, lustrous solid - The word Iodine comes from the word "iodes", which means violet in Greek - Iodine was first discovered by a French chemist named Barnard Courtois
 * Things I learned from Iodine are:**

- Super Glue was initially discovered in 1942 - Super Glue lasts longest when stored upright in dry, cool conditions like a refrigerator
 * Things I learned from Super Glue are:**
 * -** Super Glue’s maximum strength can be achieved when bonding metal to metal.
