sensitivity of liquid in glass thermometer

If you put such a thermometer into boiling water, it sort of explodes as the expanding fluid shatters the glass casing. lowest temperature = .....[1] (c) A second liquid-in-glass thermometer has the same range but it has a greater sensitivity. (1) sensitivity by increasing bulb size (& hence the thermometric liquid) OR by reducing bore diameter (2) responsiveness (and its not "responsitivity") by reducing bulb size OR reducing thickness of the glass used to make the bulb It is inside the glass body of the thermometer and is connected to the bulb. As compared to electrical thermometers, they are very weak and delicate. Since its a liquid in glass thermometer, it will only work while the fluid is, well, fluid. Types of Liquid-In-Glass Thermometers [] Introduction []. The temperature range is −80 to +330 °C depending on the liquid. You also have the option to opt-out of these cookies. The mercury thermometer is one example of liquid thermometers. The range of a liquid-in-glass thermometer is limited by the length of the thermometer and can be increased by: increasing the diameter of the capillary – this means that the liquid will not expand as … It is mandatory to procure user consent prior to running these cookies on your website. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Thermometers and temperature 16. The liquid must have the following properties: Be able to be seen easily As the temperature of the liquid in the reservoir increases, it expands and rises into the capillary tube. We'll assume you're ok with this, but you can opt-out if you wish. 3. The range can be increased by lengthening the bore. The mercury-in-glass or mercury thermometer was invented by physicist Daniel Gabriel Fahrenheit in Amsterdam (1714). GCSE Keywords: Bulb, Thread diameter, Liquid, Glass thickness. But opting out of some of these cookies may affect your browsing experience. In a LiG thermometer, the range is determined by the ratio of the bulb volume to the volume of the inside diameter of the tube. Organic liquids which are usually employed for construction of liquid-in-glass thermometers include toluene, ethyl alcohol and pentane. A smaller bulb contains less mercury and hence absorbs heat in shorter time. Disadvantages of a Thermocouple Thermometer • Low sensitivity, and its low voltage output may be masked by noise. To the left is a labelled diagram of a thermometer, you don't need to know all of the different parts of a thermometer, but I included it to help you understand. The sensitivity of a thermometer can be increased by Using a thermometer with a smaller bulb – A smaller bulb contains less mercury and hence absorbs heat in shorter time.

A mass of liquid and diameter of liquid thread B mass of liquid and length of stem C thickness of glass bulb and diameter of liquid thread More sensitive means more noticeable expansion. The sensitivity of a liquid-in-glass thermometer depends on the volume of liquid used and the diameter of the bore of the thermometer. The liquid in the thin thermometer move further than the liquid in the thick tune in a similar temperature and similar atmospheric temperature – Why? The more liquid there is, the more liquid will expand and rise in the glass tube. Alcohol is also used with this type of instrument. They are considered inapt for applications involving extremely high or low temperatures. (b) The highest temperature that this thermometer can measure is 110 °C. 20 The diagram shows a liquid-in-glass thermometer. Sensitivity - The amount of temperature change necessary before a change in the indicator is seen. Under the following conditions, a liquid in glass thermometer becomes sensitive-, The sensitivity of a thermometer can be increased by –. Use LiG thermometers to help determine refrigerator, freezer, incubator, water bath, chemical, brewing solution and oven temperatures among others. Sensitivity of a thermometer is the length of increase of the liquid per degree rise in temperature. Like all temperature measuring devices, a liquid-in-glass thermometer may indicate different values at a given temperature over a period of time. Course overview. Structure and advantages of a thermocouple. This type of thermometer was developed by a German based physicist named Daniel Gabriel Fahrenheit.It consists of mercury as a liquid filled in a glass tube. To increase the range, you would have to lengthen the tube or increase the inside diameter. GCSE Keywords: Scale, Linear, Precision, Sensitivity. The bulb should be of moderate size and the capillary tube should not be extremely narrow. Sensitivity of a thermometer is the length of increase of the liquid per degree rise in temperature. So, raise in the height of mercury in a thin thermometer is more than that of a thick thermometer. A glass bulb with thinner wall – Heat can be transferred to the bulb easily. Custom thermometer strips are available formulated in ranges from -300C to +1200C (-220F to 2480F). Range is the converse of sensitivity, i.e., the longer the range, the lower is its sensitivity. Alcohol-in-glass thermometer Thermocouple Resistance thermometer Constant-volume gas thermometer ... liquid-in-glass thermometers . The sensitivity and responsiveness can be increased by making the bulb at the bottom smaller and decrease the amount of glass surrounding it. The sensitivity of a mercury thermometer can be increased by using a smaller mercury bulb, thinner wall and smaller bore. I guess what you have mentioned here is that the range is dependent on how much liquid you have and far you allow that liquid to expand within your thermometer. Besides, they can not provide digital and automated results. Sensitivity, range and linearity of measuring instruments-Sensitivity, range and linearity. Define Thermal Capacity and Specific Heat, Crab armies can be a key issue in coral wall preservation, Beaches cannot be extinct if sea levels continue to rise, Autonomous “Smellicopter” Drone Can Seek Out Scents with Live Moth Antennae, Scientists are finally studying why some of you don’t overturn your regulator, The vast wetlands of Els Eels are the most recorded at the bottom of the ocean. So number 4, longer bore, lets you increase the range of the thermometer. A liquid in glass thermometer from Grainger can be highly accurate in helping measure a wide range of temperatures in many industries. 16 The diagram shows a liquid-in-glass thermometer.
