Why is mercury used in clinical thermometer and not laboratory thermometer?
Mercury is no longer used much in thermometers due to the poisonous compounds that it forms. When I grew up, in Chemistry at school and at the doctors there were mercury thermometers and alcohol thermometers.
What are the Uses of Mercury glass thermometer?
Mercury glass thermometers are commonly used to measure human body temperature, as well as for various laboratory and industrial applications where precise temperature measurements are required. They are also used in meteorology to measure air and water temperatures.
What element is used in high temperature thermometers?
Platinum is often used in high temperature thermometers due to its ability to maintain stability and accuracy at elevated temperatures.
What are the two most commonly found in liquid-in-glass thermometers?
The two most commonly found liquids in liquid-in-glass thermometers are mercury and alcohol. Mercury thermometers are used for high-temperature applications, while alcohol thermometers are used for lower temperatures due to their lower toxicity.
Why is alcohol used in laboratory thermometer?
Alcohol is non-toxic, economically more viable and can be easily dyed to make it more visible in the capillary tube when it undergoes thermal expansion or contraction, hence it is used in laboratory thermometers. The alcohol used is not absolute ethanol however (ethanol has a boiling point of 78 degrees Celsius, while laboratory thermometers can measure up to 110 degrees Celsius); larger chain alcohols (e.g. isopropyl alcohol) would suggestibly be preferable in this context. This is, however, an obsolete approach to measuring temperature - today, more accurate quantification of temperature may be achieved through temperature sensitive probes with digital readouts.
What is the temperature scale used on most laboratory thermometers?
Temperature scale used on most laboratory thermometers is a thermometer.

Why clinical thermometers are used to measure the temperature of boiling water?
Clinical thermometers are not used to measure the temperature of boiling water! They have a range of about 35oC to 43oC and they will explode at a temperature of about 100oC! Ordinary laboratory thermometers are used.
What are the advantages of laboratory thermometer?
Laboratory thermometers are designed for high accuracy and precision in temperature measurement. They are also versatile and can be used in a wide range of laboratory settings. Additionally, laboratory thermometers are often made with durable materials that can withstand harsh laboratory conditions.
What laboratory equipment would you use for measuring temperature?
You would use a thermometer to measure temperature in a laboratory setting. There are different types of thermometers available, such as digital thermometers, mercury thermometers, and infrared thermometers, each suitable for different applications.
What is the difference between clinical thermometer and laboratory thermometer?
Laboratory thermometers can measure wide variety of temperature, whereas a clinical thermometer has a range between 95 to 105 Fahrenheit. Clinical thermometers are made to be used in a hospital to accurately determinebody temperature. They are often digital. Lab thermometers are made of metal or glass and usually don't give you an accurate reading as much as a "ball park". Clinical thermometer may have mercury but lab thermometers usually have alcohol .
What are similarities and differences between laboratory and clinical thermometer?
Both laboratory and clinical thermometers are designed to measure temperature, but they serve different purposes and have distinct characteristics. Laboratory thermometers typically measure a wider range of temperatures and are often used for scientific experiments, while clinical thermometers are specifically designed for measuring human body temperature and usually have a narrower range. Additionally, laboratory thermometers may use various scales like Celsius or Fahrenheit, while clinical thermometers are often calibrated to display body temperature in a precise manner. Furthermore, clinical thermometers might include digital displays for ease of reading, whereas laboratory thermometers can be either analog or digital.
Why their is klink absent in laboratory thermometer?
Klink is absent in laboratory thermometers because they are designed for precise measurement of temperature over a wide range, and do not require the klink mechanism found in household thermometers. Laboratory thermometers often use other types of temperature sensing elements, such as mercury or digital sensors, to provide accurate temperature readings.
What are the different kinds of uses of the laboratory thermometers?
Checking the temperature of any liquid
What are the instruments used to measure temperature of cells?
Common instruments used to measure the temperature of cells include thermometers, thermocouples, infrared thermometers, and thermal imaging cameras. These instruments can provide accurate temperature readings in various settings, from laboratory experiments to industrial applications.
