thermometer
between the grill and the condenser
While the Greeks made simple thermometers (instruments for measuring temperature) as early as the first century B.C., Italian astronomer (a scientists specializing in the study of the stars, planets, and heavenly bodies) Galileo Galilei (1564-1642) is credited with inventing the modern thermometer. Called an air thermometer, it was a device in which a colored liquid was driven down by the expansion of air. As the air got warmer and expanded, the liquid dropped. In 1612 Italian physician Santorio Santorio (1561-1636), a friend of Galileo, adapted the device to measure the body's change in temperature due to illness. A century later, in 1714, German physicist Daniel Fahrenheit (1686-1736) invented the mercury (a metallic element) thermometer. Thermometers in use today, contain liquid mercury, which rises as it gets warmer. Galileo Galilei is often claimed to be the inventor of the thermometer. However the instrument he invented could not strictly be called a thermometer: to be a thermometer an instrument must measure temperature differences; Galileo's instrument did not do this, but merely indicated temperature differences.
The mercury in the bulb at the bottom of the thermometer expands or contracts depending on the amount of heat (the temperature). The narrow calibrated tube that you read the temperature on acts to amplify this effect. The calibration is usually either in Fahrenheit or Celsius.
From a thermometer. Note! Mercury can enter your body through the skin and there is no ay to remove it. Don't touch it!!
you dont need a thermometer
you dont
No you dont add or subtract anything.
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
i dont no just leave me alone
if you dont put the whole bulb in, then the thermometer cant read the temperature accurately.
take a regular thermometer and put special gel on it (you can usually buy from vet) after that stick into dogs bottom take out thermometer when it beeps clean it really good afterwards
Daniel Gabriel Fahrenheit invented the mercury thermometer in 1714.many inventers invented there own version of the thermometer but the mercury themometer i think most likely is just a regular thermometer you put in someones mouth under there toung. The regular inventor of the thermometer that you put in your mouth is some spanish named guy called Santorio but i dont reallt know his last name
Celsius, Fahrenheit, and Kelvin.
please study your lesson and listen to your teacher when she/he is teaching....dont chatwith your friend whille teaching so that you dont need to research understandddddddddddddddddd
