Discuss why mercury was used for clinical thermometers and why it is no longer used for that purpose?
It was used because it worked very well. It gave hery accurate results fairly quickly, for low cost, and they would work very reliably for a very long time.
It's no longer used because then a thermometer is broken or retired, it's considered difficult to dispose of the Mercury safely.
People (even environmental professionals) are very afraid of mercury, even though there is no evidence that it's actually harmful if not inhaled or swallowed.

What is the purpose of mercury thermometers?
Mercury thermometers are used to measure temperature accurately. The expansion of mercury in the glass tube allows for easy visualization of temperature changes. However, due to the toxic nature of mercury, these thermometers are being phased out in favor of digital thermometers.
Is there mercury in thermometers today?
Most modern thermometers no longer use mercury due to its toxicity. Instead, digital thermometers, infrared thermometers, and other types of thermometer technology that do not contain mercury are widely available and recommended for safer use.
What are the names of the thermometer?
Common types of thermometers include digital thermometers, infrared thermometers, and mercury thermometers. Each type serves the purpose of measuring temperature but may vary in application and accuracy.
Is a clinical thermometer a type of analog thermometer?
Yes, a clinical thermometer is a type of analog thermometer. Analog thermometers use a liquid-filled bulb to measure temperature and display the reading on a scale marked with numbers. Clinical thermometers are typically designed for measuring human body temperature and often come with a narrow range of temperatures suitable for this purpose.
What is the purpose of the bent constriction in the clinical thermometer?
The bent constriction in the clinical thermometer allows for the expansion and contraction of mercury or alcohol in response to temperature changes. This design prevents the column of liquid from falling back down too quickly, ensuring an accurate reading can be taken by the healthcare provider.

What instrument measures temperature outside?
A thermometer measures temperature, indoor or outdoor.
What is the main purpose for mercury?
Mercury is primarily used in electrical switches and relays, thermometers, barometers, and fluorescent lights. It is also used in the production of industrial chemicals like caustic soda and chlorine.

What is the purpose of the 'kink' in clinical thermometer?
In a normal Mercury thermometer, the mercury moves up and down the capillary as the temperature changes and thus if you removed it form contact with the patient the reading would steadily fall as it cooed. As you need a medical thermometer to give you a reading of the patients temperature even after it has been removed form the patient, you need to stop the mercury shrinking back into the reservoir. The 'kink' does this, it breaks the connection between the mercury in the capillary and the reservoir so the reading given is accurate. On the other hand before it can be used again the mercury in the capillary has to be vigorously shaken back into the reservoir. On a point of interest, clinical mercury thermometers (with the 'kink') are getting very rare because they have been phased out due to concerns regarding mercury poisoning should hey break in use.
What is the different between clinical thermometer and liquid in glass thermometer?
a lab thermometer did not have a constriction as compared to clinical thermometer. it have a wide range of measurement and usually contains alcohol
What is the purpose of the bent constriction in the clinical thermometer?
The bent constriction in the clinical thermometer allows for the expansion and contraction of mercury or alcohol in response to temperature changes. This design prevents the column of liquid from falling back down too quickly, ensuring an accurate reading can be taken by the healthcare provider.
What is the purpose of medical or clinical coding?
The purpose of medical or clinical coding enables patients' medical information to be classified. Then the information can be shared and understood by governments and healthcare organizations.
What is the purpose of a clinical governance?
Clinical governance has a very important purpose in the medical field. It is used to ensure the maintenance and improvement of patient care. It first became popular in 1995.
Difference between mercury and alcohol?
Mercury is an element, a metal. Alcohol is the name of a familty of organic compounds made up of carbon, oxygen, and hydrogen atoms in various combinations. The only obvious similarity of the two substances is that some alcohols (ethyl alcohol, or ethanol, C2H5OH, for example ) share a common freezing point with mercury of about minus 40 degrees (Celsius or Fahrenheit), making them suitable for use in outdoor thermometers.
