Why is mercury not suitable for thermometers in Canada?
Concerns about the element's toxicity have led to mercury thermometers being largely phased out in clinical environments in favor of alcohol-filled or digital ones.
What different types of thermometers exist?
Contributed by 1st grader Mackenzie and her mom Julie: There are circle thermometers which are like a clock and you read the numbers from left to right. There are stick thermometers that go under your tongue, your arm pit or other body parts. The numbers go from bottom to top. There are digital thermometers that can go in your ear, on your finger or other body parts. There are inside thermometers and outside thermometers to tell the general warmth/coolness of the space/environment. There are different scales - Fahrenheit and Celsius. Thermometers may be used to take a person's body temperature, to tell how warm/cold it is outside or in a room, to test whether food is cooked to a desired temperature to be safe. We hope we helped you.
What chemical element is used in thermometers?
the element used in termometers is Mercury.
What do they use instead of mercury in thermometers?
There are a variety of cost-effective, mercury-free alternatives available at local pharmacies. These alternatives include digital, glass gallium-tin, and glass alcohol thermometers. Because of the health risks associated with mercury exposure from broken thermometer, it is very difficult any more to find glass mercury thermometers.
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 difference between digital and mercury thermometer?
Digital thermometers measure electrical resistance and Mercury thermometers measure thermal expansion.
How are mercury thermometers used today?
Mercury thermometers are rarely used, except in lab thermometers. For human use, they have been replaced by dyed alcohol glass thermometers, or electronic digital thermometers.
What's the difference between a regular and an electronic thermometer?
Electronic thermometers have a digital readout, whereas a regular thermometer is most likely not.
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 .
Are digital and clinical thermometers same?
no,digital thermometers don't have mercury whereas clinical thermometers have mercury.
What are modern thermometers made of?
Modern thermometers are typically made of materials such as glass, plastic, or metal. The most common type of modern thermometer is the digital thermometer, which includes a temperature sensor and a digital display screen. Other types of modern thermometers may contain mercury or alcohol as the temperature-sensitive material.
Why is mercury not suitable for thermometers in Canada?
Concerns about the element's toxicity have led to mercury thermometers being largely phased out in clinical environments in favor of alcohol-filled or digital ones.
What is used to measure temperature of the weather?
There are many instruments that meteorologists use to measure weather. The two most commonly used instruments are a barometer and a thermometer.
Different types of thermometers?
Celsius and Fahrenheit Thermometers Clinical Thermometers Ear (Tympanic) thermometers Pacifier Thermometers Underarm or Oral Thermometers Food Thermometers Outdoor Thermometers Mechanism of Different Types of Thermometers Mercury and Alcohol Thermometers Digital Thermometers Alcohol thermometer Beckmann differential thermometer Bi-metal mechanical thermometer Electrical resistance thermometer Galileo thermometer Infrared thermometer Liquid Crystal Thermometer Medical thermometer (e.g. oral thermometer, rectal thermometer, basal thermometer) Mercury-in-glass thermometer
What are the uses of the digital thermometers?
They're thermometers..... So.... They do the exact same things as normal thermometers, except the temperature comes out on a small, digital screen. -.-
Why are digital thermometers used these days?
Digital thermometers have replaced mercury thermometers because mercury is toxic. [Personal commentary: digital thermometers are not accurate and mercury thermometers are so how many people are being harmed by not knowing their temperature versus how many would be harmed by the mercury if accurate thermometers were still used?]
What is the differences between a clinical thermometer and a laboratory thermometer?
