Consider the following statements:
- Due to high heat capacity of clinical thermometer, it measures change in body temperature.
- Leaching is the process of extracting minerals from a solid by dissolving them in a liquid.
Which of the given statements is/are correct?
-
Only (1)
-
Only (2)
-
Both (1) and (2)
-
Neither (1) nor (2)
B
Correct answer
Explanation
Statement (1) is wrong. Clinical thermometer has low heat capacity, i.e. mercury (present in thermometer) has less specific heat to warm up. Therefore, thermometer measures even the small change in body temperature.
Statement (2) is correct. Yes, leaching is the process of extracting minerals from a solid by dissolving them in a liquid. Uranium and gold are extracted from their ores by chemical leaching.
