Question

Why do we pluck a clinical thermometer before we measure body temperature?

Answer 1

Hello friend !!!!

Here's the answer you are looking for

We pluck the clinical thermometer to bring the Mercury level to zero or the mean starting point so that the temperature measured is accurate and without any error.

If we don't pluck it and simply start measuring the temperature then the level of Mercury initially may not be at the 0℃ and hence may result in giving wrong measurements.
