  • Question

  • Assertion (A)
    Alcohol rather than mercury is used in a thermometer to measure a temperature of - 60 C.
    Reason (R)
    Alcohol has a lower freezing point than mercury.


  • Options
  • A. if both A and R are true and R is the correct explanation of A
  • B. if both A and R are true and R is not the correct explanation of A
  • C. if A is true but R is false
  • D. if A is true but R is true

  • Correct Answer
  • if both A and R are true and R is the correct explanation of A 

    Explanation

    We know that, mercury freezes at -39 C, while alcohol freezes at a point far below - 100 C. So, alcohol is used to measure lower temperatures. Similarly, mercury boils at 357 C, while alcohol boils at 78 C. So, mercury is used to measure high temperature.
