Match the following (a) Laboratory Thermometer (i) Avoids use of mercury (b) Clinical Thermometer (ii) To measure the boiling point of water (c) Digital Thermometer (iii) To check the temperature of atmosphere around (d) Maximum Minimum Thermometer (iv) To check body temperature Correct Answer (a) - (ii), (b) - (iv), (c) - (i),(d) - (iii)

Concept:

Thermometer

  • Temperature is the physical quantity that measures the hotness or coldness of a body. 
  • Temperature is measured using a thermometer.
  • The thermometer usually contains mercury which expands on heating. 
  • Temperature is measured by measuring mercury levels on the scale. 
  • Measurement of temperature is done on various scales like degree Celcius, degree, Farhenhite degree, and Kelvin.


Clinical Thermometer

  • The thermometer is used to measure body temperature. 
  • It is having a range that is around human body temperature. 
  • The range is 37 °C to 42°C. 
  • It is having a kink that does not let the mercury of level get down just after the reading. 


Laboratory Thermometer

  • The laboratory thermometer is having ranges from - 10 °C to - 110 °C. 
  • It is used in chemistry laboratories to measure the boiling point or melting point of substances. 
  • It does not have a kink as the clinical thermometer. 


Maximum and Minimum Thermometer

  • This thermometer is used to measure the atmospheric temperature.
  • The name has been given as it measures the maximum and minimum temperature of the day. 
  • It is used by the weather department. 


Digital Thermometer

  • Mercury is a poisonous liquid. 
  • To avoid the use of mercury digital thermometer is used. 
  • The temperature is displayed in form of a digital display.
  • It is based on fact that the temperature increase increases the electric resistance. 
  • This change in resistance causes a change in current. The variation is detected by electronic sensors. 


Conclusion:

(a) Laboratory Thermometer

(ii) To measure the boiling point of water

(b) Clinical Thermometer

(iv) To check body temperature

(c) Digital Thermometer

(i) Avoids use of mercury

(d) Maximum Minimum Thermometer

(iii) To check the temperature of the atmosphere around


The correct option is a) - (ii), (b) - (iv), (c) - (i),(d) - (iii)

Read the following passage and answer the item that follows. Your answers to this item should be based on the passage only. We live in digital times. The digital is not just something we use strategically and specifically to do a few tasks. Our very perception of who we are, how we connect to the world around us, and the ways in which we define our domains of life, labour and language are hugely structured by the digital technologies. The digital is everywhere and, like air, invisible. We live within digital systems, we live with intimate gadgets, we interact through digital media, and the very presence and imagination of the digital has dramatically restructured our lives. The digital, far from being a tool, is a condition and context that defines the shapes and boundaries of our understanding of the self, the society, and the structure of governance. Which among the following is the most logical and essential message conveyed by the above passage?
