They include the thermal expansion of solids or liquids with temperature, or the change in pressure of a gas on heating or cooling. Radiation-type thermometers measure the infrared energy emitted by an object, allowing measurement of temperature without contact.Thermometers are widely used in industry to control and regulate processes, in the study of weather, in medicine, and scientific research.he precision or resolution of a thermometer is simply to what fraction of a degree it is possible to make a reading. For high temperature work it may only be possible to measure to the nearest 10 Â°C or more. Clinical thermometers and many electronic thermometers are usually readable to 0.1 Â°C.
The temperature of the air is a measure of how quickly the molecules are moving. The more energy of motion the molecules have, the higher the temperature you feel in the air. Air temperature is measured with thermometers.Common thermometers consist of a glass rod with a very thin tube in it. The tube contains a liquid that is supplied from a reservoir, or bulb, at the base of the thermometer. Sometimes the liquid is mercury, and sometimes it is red-colored alcohol.he tube is marked with a scale, in degrees Fahrenheit or in degrees Celsius. When you are measuring the air temperature, be sure to have the thermometer in the shade. If the sun shines on the thermometer, it heats the liquid. Then the reading is higher than the true air temperature.
