Gas Chromatography (GC) Definition: Gas chromatography is a physical method of separation in which the components to be separated are distributed between two phases‚ one being a stationary bed of large surface area‚ and the other a gas that percolates through the stationary bed. When the stationary phase is a solid‚ the separation process is more precisely called gas-solid chromatography. Introduction: Gas Chromatography is a technique widely used to separate complex mixtures of substances. Compounds

In the 18th and 19th centuries scientists wrestled with identifying and describing the nature of the “stuff” that produced change. One concept that became popular for a while was that of “caloric” (what we now call heat). “Caloric was originally conceived of as a quantity that would flow from a hotter object to a cooler one that would warm up as a result. It answered the need for a way for the cause of warming to get from here to there. Not only did caloric serve as a cause for warming‚ it

Batteries contain heavy metal such as mercury‚ cadmium and nickel which can contaminate the environment when batteries are improperly disposed of. When flamed‚ certain metals might be release to the air or be left in the ash of the burnt battery. By draining and neutralising acid from the batteries and recycling them our problem is solved. The one world factors I shall be looking at this from is environment and economic. By: www.leadbatteryuniversity.uk Batteries must always be drained before

Kierra Roberts 1-4-11 11B How Do Batteries Work? Electricity is the flow of electrons through a wire‚ that is called a circuit. Batteries have three parts to them‚ an anode‚ a cathode‚ and an electrolyte. The cathode and the anode are hooked up to an electrical circuit. The chemical reaction that is happening causes the electrons to build up at the anode. When the circuit is closed the electrons will be able to get to the cathode. When the electrochemical process change the
