The Strange History of the Invention of the Thermometer Time
WebbLinné had a great interest in thermometers, and he ordered a thermometer with the modern scale from the instrument maker Daniel Ekström around 1744. The scale is mentioned in … WebbIn 1603 the renowned scientist Galileo Galilei invented a thermoscope. The thermoscope he invented worked on the principles of buoyancy and gravity. The Galileo thermoscope had water with hand blown glass bulbs, filled with a coloured liquid for…show more content… The thermoscope did not have a scale at all. A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object). A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which … Visa mer While an individual thermometer is able to measure degrees of hotness, the readings on two thermometers cannot be compared unless they conform to an agreed scale. Today there is an absolute thermodynamic temperature scale. … Visa mer Thermometers may be described as empirical or absolute. Absolute thermometers are calibrated numerically by the thermodynamic absolute temperature scale. Empirical thermometers are not in general necessarily in exact … Visa mer The precision or resolution of a thermometer is simply to what fraction of a degree it is possible to make a reading. For high temperature … Visa mer Thermal expansion Utilizing the property of thermal expansion of various phases of matter. Pairs of solid metals with different expansion coefficients can be used for bi-metal mechanical thermometers. Another design using this principle is Breguet's thermometer. Some … Visa mer Traditional thermometers were all non-registering thermometers. That is, the thermometer did not hold the temperature reading after it was moved to a place with a different … Visa mer A thermometer is called primary or secondary based on how the raw physical quantity it measures is mapped to a temperature. As … Visa mer Thermometers can be calibrated either by comparing them with other calibrated thermometers or by checking them against known fixed points on the temperature scale. The best known of these fixed points are the melting and boiling points of pure … Visa mer summer walker life on earth download
