A liquid thermometer and an electronic thermometer are both properly placed in the same liquid. The liquid thermometer shows 53.4 degrees Celsius and the electronic thermometer shows 58.2 degrees Celsius. Which could best explain why they show different readings? btw its from edgenuati
Answers
It's probably not a question of units because the conversions here from C to F or K do not give the right numbers. An electronic thermometer (as with most electronic measuring devices) need to be calibrated regularly to some sort of reference point. A liquid thermometer works based on the actually physical properties of the liquid inside it, and so will always display the same values - no calibration required!
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.
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.
3. Digital thermometers are safer to use
Another reason digital thermometers, such as the ThermoPro Digital Thermometer, are becoming a more popular choice over mercury thermometers is because they are also safer to use.
Mercury thermometers are most often made of glass, which is inserted into food to gauge the temperature. However, glass is very fragile, which means, it can easily become broken. Mercury is a toxic chemical, which if released could contaminate the body as well as surrounding areas, rendering it unsafe. It is also difficult to clean up. In fact, mercury thermometers are being phased out by a number of countries across the globe and not allowed to be sold to customers due to the hazard they pose
