The thermometer is mainly used in order to measure the temperature of different objects. If you don’t feel OK taking a rectal temperature, use another method. The instrument is made up of two components. The adiabatic evaporation of water from the thermometer bulb and the cooling effect is indicated by a "wet bulb temperature" lower than the "dry bulb temperature" in the air. When air around the tube heats the liquid, the liquid expands and moves up the tube. Thermopile 2. Table shows a comparison between temperature … Thermistors change their electrical resistance as the temperature rises and falls so an increase or decrease in the voltage across a thermistor correlates with a rise or fall in temperature. People normally use the thermometer to check their current temperature. Evaporation cools this thermometer below the actual air temperature, recorded on the dry thermometer. A WEATHER BALLOON measures weather conditions higher up in the atmosphere. These easy-to-read that instrument used to measure temperature record humidity without interference. Means, Tiffany.
