What is the use of thermometer Class 7?

What is the use of thermometer Class 7?

Thermometer is a device which is used to measure temperature. Thermometer is made of a long narrow glass tube, with a bulb at one end. The narrow tube appears as a continuous silver line, because it is filled with mercury.

What are the types of thermometer and their uses?

The different types of medical thermometers

  • Digital thermometer. Digital thermometers work by using heat sensors that determine body temperature.
  • Oral thermometer.
  • Digital ear (tympanic) thermometer.
  • Forehead (temporal) thermometer.
  • App-based thermometer.
  • Pacifier thermometer.
  • Mercury (liquid in glass) thermometer.

What are the two types of thermometer?

There are different types, but not all thermometers are right for your child.

  • Digital thermometers.
  • Ear (or tympanic) thermometers.
  • Infared thermometers.
  • Strip-type thermometers.
  • Mercury thermometers.

    What are the features of thermometer?

    A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in which some change occurs with a change in temperature; and (2) some means of converting this change into a numerical value (e.g. the visible scale …

    What are the two main types of thermometer?

    What are the different types of thermometer?

    • Digital thermometers. Digital thermometers are regarded as the fastest and most accurate type of thermometer.
    • Electronic ear thermometers.
    • Forehead thermometers.
    • Plastic strip thermometers.
    • Pacifier thermometer.
    • Glass and mercury thermometers.

    How is a thermometer used in everyday life?

    These thermometers are used to measure both body temperature and a different material. The mercury inside them expands and contracts with changes in temperature. This thermometer is able to measure the temperature of the air, without the result being affected by any object around it.

    How are infrared thermometers used to measure temperature?

    All of the ones we have mentioned above require contact to determine temperature. An infrared thermometer uses thermal radiation that objects emit to measure temperature. This means that they can tell temperature from a distance. Some people call them ‘temperature guns’ as most are handheld and look like miniature guns.

    How is a clinical thermometer used in medicine?

    Clinical thermometers, also known as medical thermometers or doctors’ thermometers, are used to take body temperatures in humans and animals2. Many newer thermometers use infrared radiation to record temperature at alternative points, such as the eardrum or forehead2.

    Can a thermometer be used to determine the temperature of food?

    You can also use a thermometer to figure out the temperature of your food while cooking. There are various types of thermometers, depending on the sphere of use and the mechanism involved in determining the temperature. We will tell you about most common types of thermometers.

    What is the best type of thermometer?

    The best ways are in the mouth, ear, underarm, or temporal (forehead). Digital electronic thermometers are the easiest and most accurate type of thermometer to use. Do not use mercury or glass thermometers. A normal temperature is 98.6°F (37°C) but can range from 97.2°F to 99.9°F (36.2°C to 37.7°C).

    What is the purpose of a thermometer?

    Thermometers are normally used to measure the temperature of one’s body. This device is traditionally found in clinics, hospitals, pharmacies and homes for this purpose. It helps in recording the temperature of the body at different times, in case of fever caused by various types…

    What is used in thermometers?

    Mercury is one of the most familiar materials used in liquid thermometers. Other liquids, such as kerosene or ethanol, may also be used in these types of thermometers. When heat rises, the liquid expands from a bowl or bulb into the empty area, climbing up the tube.

    What does a thermometer do?

    A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object).
