Ratified in 1791, the Ninth Amendment is an outgrowth of a disagreement between the Federalists and the Anti-Federalists over the importance of attaching a Bill of Rights to the Constitution.he language and history of the Ninth Amendment, Goldberg wrote, demonstrate that the Framers of the Constitution intended the judiciary to protect certain unwritten liberties with the same zeal that courts must protect those liberties expressly referenced in the Bill of Rights.
A THERMOMETER measures the air temperature. Most thermometers are closed glass tubes containing liquids such as alcohol or mercury. When air around the tube heats the liquid, the liquid expands and moves up the tube. A scale then shows what the actual temperature is. A BAROMETER measures air pressure. It tells you whether or not the pressure is rising or falling. A rising barometer means sunny and dry conditions, while a falling barometer means stormy and wet conditions. An Italian scientist named Torricelli built the first barometer in 1643.
They are sometimes called laser thermometers if a laser is used to help aim the thermometer, or non-contact thermometers or temperature guns, to describe the device's ability to measure temperature from a distance. non-adjustable thermometer may be used to measure the temperature of a reflective surface by applying a non-reflective paint or tape, with some loss of accuracy. A sensor with an adjustable emissivity setting can also be used to calibrate the sensor for a given surface, or to measure the emissivity of a surface.
