Question

Aman got a naughty idea. He wanted to measure the temperature of hot milk using a clinical thermometer. His friend stopped him from doing so. Why? b) What is the temperature range of this thermometer? c) State any two precautions used while using this thermometer. d) What is the purpose of a kink in a thermometer? e) Dia’s mother wanted to note his body temperature. She gave few to the thermometer before taking the reading. What could be the reason?

Answer 1

Temperature range: 35-42°C

Precautions:

1) Make sure the mercury level is below 35°C

2) Handle with care, the mercury in the thermometer is toxic.

The kink prevents the rapid falling of the mercury back into the bulb of the thermometer. Hence we can measure the temperature of the body accurately and conveniently even if the thermometer is taken out from the body.

The question isnt clear, She might have shaked it to let the mercury settle.
