Give any three differences between a mercury thermometer and a digital thermometer.
Answers
Answer:
read it carefully it is very useful but it is long.
Explanation:
Thermometers have various uses from gauging food temperatures to gauging body temperatures and more. But when it comes to selecting a thermometer, which is best, a digital thermometer or a mercury thermometer? Well, as it turns out, the type of thermometer you choose does indeed have a significant impact on your temperature reading as well as your all-around safety, so let’s take a look at the following digital thermometer and mercury thermometer comparison to check out a few reasons why.
Digital Thermometer vs. Mercury Thermometer
Mercury thermometers have been around for quite some time; however, as of recent, digital thermometers have begun to take over, which is cause for us to research their benefits over mercury thermometers. In fact, digital thermometers have several advantages over traditional mercury thermometers, which the following comparisons will reveal.
Why is a Digital Thermometer Better Than a Mercury Thermometer?
1. Digital thermometers provide faster results
Digital thermometers provide fast results as opposed to mercury thermometers whose readings are slower to realize because you have to wait for the mercury to heat and then slowly rise to display the temperature. However, digital thermometers are designed using advanced technology that enables them to provide instant results on the spot, which means no more waiting for crawling hot liquids to rise.
mercury thermometer theory
Mercury thermometers are designed utilizing the idea that mercury expands with heat.
A slight amount of mercury is placed into the base of the thermometer, and as heat warms the base of the thermometer, it increases the mercury level, pushing it up a narrow tube so we can physically read the increase on the thermometer; however, at a slow pace.
Mercury is used because it remains liquid throughout various temperatures as opposed to water, which freezes in colder temperatures. Mercury thermometers are also designed to withstand boiling temperatures.
2. Digital thermometers provide better accuracy
Besides the fact that digital thermometers provide faster readings, they are also slowly replacing conventional mercury thermometers because they include various technologies that provide better accuracy, which has even made them a popular choice for various professional industries. In fact, some digital thermometers also include thermocouple sensors on the probe that have been measured and calculated to provide very high accuracy and without the need for calibration like mercury thermostats.
Calibration refers to the measurement that is performed on a thermometer to check the readings. Once the thermometer is tested, it is then adjusted or re-calibrated so that it provides the proper reading. To do so, the thermometer is placed in a boiling hot or ice cold bath for adjustment using the temperatures.
