A history and importance of thermometers

A thermometer is a tool which measures both the temperature and the temperature gradient it consists of a temperature sensor usually made of mercury that changes when the temperature changes too it also has a numeric scale, so you can see how big the change of the temperature is. Who invented the thermometer the first recorded thermometer was produced by the italian, santorio santorio (1561-1636) who was one of a group of venetian scientists working at the end of the sixteenth century as with many inventions the thermometer came about through the work of many scientists and was improved upon by many others. A maximum thermometer is a familiar type of liquid thermometer in a maximum thermometer, the liquid is pushed up the glass tube, but cannot fall easily when the temperature lowers in a maximum thermometer, the liquid is pushed up the glass tube, but cannot fall easily when the temperature lowers. Temperature is a major determining factor of global climate patterns it affects the life cycles of plants and animals, influences weather and tides, and controls the freeze and thaw of the polar ice caps a small change in average temperature can have powerful effects on the environment worldwide.

  • How thermometers work ­ the bulb thermometer is the common glass thermometer you probably grew up with the thermometer contains some type of fluid, generally mercury bulb thermometers rely on the simple principle that a liquid changes its volume relative to its temperature.
  • Important elements, the temperature sensor (eg the bulb on a mercury thermometer) in which some physical change occurs with temperature, plus some means of converting this physical change into a value (eg the scale on a mercury thermometer.
  • A brief history of thermometers before the thermometer as we know it came along, several inventors including galileo galilei developed something known as a thermoscope this device, which came about toward the end of the 16th century, could show its user that something was getting hotter or colder, but it contained no set measurements.

The history of the thermometer before thermometers discovered, astronomers and physicists made great efforts to be able to create a tool that can measure the temperature they know that temperature can make the substance expands. A thermometer is an instrument for measuring or indicating temperature (how hot or cold something is) one type of thermometer is a narrow, concealed glass tube containing mercury or alcohol which extends along the tube as it expands another type is a digital thermometer, which uses electronics to measure temperature. Thermometers measure temperature, by using materials that change in some way when they are heated or cooled in a mercury or alcohol thermometer, the liquid expands as it is heated and contracts when it is cooled, so the length of the liquid column is longer or shorter depending on the temperature. A thermometer is an instrument used to measure temperate they can be used for outdoor purposes or to see if someone is running a fever they are found virtually anywhere where temperature.
