2. what are the uses of thermometer?
3.what is the difference between clinical and ordinary thermometer?
4.why clinical thermometer has a kink in its capillary tube?
Answers
Explanation:
1....A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object) 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 ...
2...Thermometers are used to see if you have a fever or tell you how cold it is outside. Made up of thermo (heat) and meter (measuring device), the meaning of the word thermometer is pretty straightforward. Thermometers measure temperatures in degrees, according to either the Celsius or Fahrenheit system.
3....
The difference between an ordinary thermometer and a clinical thermometer is that an ordinary thermometer will measure and substance at any given temperature. The clinical thermometer will measure human body temperatures only.
4...A clinical thermometer has a narrow kink in the capillary tube because when Mercury expands, it pushes through the kink, but when it's taken out of patient mouth, Mercury does not go back to the bulb beacuse if it. Hence, doctor can read the patients temperature easily .
have you got answer thanks for support
Answer:
1)an instrument for measuring temperature.
2)A thermometer is a device used for measuring temperature. This ice-covered thermometer shows that the temperature is about 0 degrees Celsius, or 32 degrees Fahrenheit.
3)The difference between an ordinary thermometer and a clinical thermometer is that an ordinary thermometer will measure and substance at any given temperature. The clinical thermometer will measure human body temperatures only.
4)Kink in the Mercury thermometer helps to prevents the falling of mercury present in capillary tube into bulb. It ensures that the user takes the correct reading of temperature
