Flame Test Lab Question: When a compound is placed in the flame of a burner‚ what happens to the color of the flame? Hypothesis: When the compound is placed in the flame‚ the flame changes color depending on the chemical compound. When they’re heated‚ they gain energy and changed color sometimes. Safety Requirements for this Lab: Wear goggles at all times. If you want to remove them to write in your notebook you may sit at a table in the center of the room. When you sit down remove them

Panda signatures: * Slumped spine. * Mask. * Feet point inward. * Neck slightly forward. * Big bodied‚ wide. * Slow rhythm * Peaceful and playful intention. Reflection I found finding an animal and engulfing it as I am quite enjoyable‚ as pandas have been my favourite animal since a very young age I was confident on its movements‚ behaviours and signatures. I experimented with a panda ‘looking

if you will would be that it can be used for high-speed‚ heavy-duty‚ high temperature cutting tools‚ and for dies. Cobalt is also used in other magnetic steels and stainless steels‚ and in alloys used in jet turbines and gas turbine generators. The metal is used in electroplating because of its appearance‚ hardness‚ and resistance to oxidation. This makes it an ideal element for anything involving extremely high temperatures and heavy mechanical work as stated earlier. Environmentally‚ trace amounts

the tangled chains in the amorphous region are frozen so movement of chains is not possible the polymer is brittle. If the glassy material is heated‚ the chains reach a temperature at which they can move. This temperature is called the glass transition temperature. Above this temperature the polymer is flexible. At the melting point‚ the crystalline regions break down and the polymer becomes a viscous liquid. The Physical Properties of a Polymer Depends on: Chain Length The physical properties

United States until 1957 when it was observed by Philipchuck that metal sheets that were being explosively formed would occasionally stick to other metals. Over the decades the process has been developed fully with large applications in the manufacturing industry. Explosive welding is a solid-phase process where welding is accomplished by accelerating one of the components which produces high velocity interactions of dissimilar metals by a controlled detonation. By doing this the resultant composite

Introduction Metals undergo natural destruction that allows a spontaneous deteriorating reaction where they return to their original state from where they are obtained upon contact with the surrounding‚ particularly when reacted to oxygen. Such phenomenon is known as corrosion (Zumdahl‚ 1998). This leads the surface of the materials to rust in due time. Usually‚ this kind of process is electrochemical but is sometimes accompanied by mechanical and physical stress that causes the metal to corrode (Heitz
