Fixed point of a thermometer
WebThe fixed points used in temperature scale are: (i) Lower fixed point or ice point or freezing point and. (ii) Upper fixed point or steam point or boiling point. (i) Lower … WebAt the defining fixed points this deviation is obtained directly from the calibration of the thermometer: at intermediate temperatures it is obtained by means of the appropriate deviation function {Eqs. (12), (13) and (14)}. (i) - For the range 13.8033 K to 273.16 K the following reference function is defined: 12

Lower fixed point: The temperature at which the fluid (like mercury in the mercury thermometer) used in the thermometer is contracted maximum and cannot contract further and its level becomes …
The precision or resolution of a thermometer is simply to what fraction of a degree it is possible to make a reading. For high temperature work it may only be possible to measure to the nearest 10 °C or more. Clinical thermometers and many electronic thermometers are usually readable to 0.1 °C. Special instruments can give readings to one thousandth of a degree. However, this p… WebApr 4, 2024 · T e m p e r a t u r e, t = 90 180 × 100 = 50 ∘ C So, the correct answer is “Option B”. Additional Information: To define a temperature scale in a thermometer, we need to choose two reference points, which are known as fixed points. In Celsius scale these fixed points are defined using properties of pure water.
