are many different types of thermometers; however each one is based on a physical property of a thermometric (temperature measuring) substance that differs in a measurable way with temperature. Some of the physical properties that vary with temperature are volume‚ resistance and color. A physical property that increases or decreases with temperature can be used to measure temperature. This is called a thermometric property. Liquid-In-Glass Thermometers There are two types of liquid-in-glass

1989‚ a McDonnell Douglas DC-10-10 operated by United Airlines experienced a catastrophic failure of the number 2 tail-mounted engine during cruise flight. The catastrophic failure led to engine debris severing all three flight control hydraulic lines resulting in total hydraulic loss. The pilots were subsequently unable to control the airplane‚ except by manipulation of the throttles to vary engine thrust‚ resulting in a crash landing. The NTSB determined that the probable cause of the accident

fracking? Well; it gets its name from “Hydraulic Fracturing‚” and this is the process by which fossil fuels‚ usually natural gas or petroleum‚ are extracted from the earth. During this process‚ drilling from a well into hard shale rock takes place‚ and then that rock is cracked. This cracking releases the fossil fuels inside the shale rocks. Water‚ sand and chemicals are injected into the cracked rocks at high pressure. Ultimately the injection forces the gas or oil to flow out of the well(CNN 2012)

Although there are a couple different types of chromatography‚ in each case a substance is placed onto or into a medium and a solvent is passed through the test substance. In chromatography science‚ the solvent is called the mobile phase or the carrier fluid and the medium is called the stationary phase. There are four main types of chromatography; these are Liquid Chromatography‚ Gas Chromatography‚ Thin-Layer Chromatography and Paper Chromatography. Chromatography
