Answer:

A) a doctor dips the thermometer in a liquid before use because are 2 reasons (1) is that any infections of the previous patinet may have does not infect others(2)the mercury level should fall down to below 35 degrees.(2) answer to give a true reading of inner body heat because the intense heat of our body is present under our tongue.domestic animal have a 38.5 degrees celsius & birds have a 37.7.c

B) Thermometer is kept under tongue so that the reading which it gives is true , i.e. true reading of the inner body heat. The intense heat of our body is present under our tongue and so it is used under tongue so that we can measure our whole body temperature . The underside of the tongue has the most bloodflow and is more accurate than any part of the mouth. If thermometer will be in contact with air at the same time , then it will cool down and will result in giving incorrect reading. So it is kept under tongue.

C) The body temperature can be measured by keeping the thermometer at some other place than the mouth:

1. We can use temperatures by placing thermometer under arms..

 2. For Infants, doctors uses thermometer near ear to measure temperature.

3. On fore head of person where thermometer is kept to record temperature.

D) Different body parts have different temperatures and this is evident when a person gets fever.

Tongue is always at least 2 degree cooler than armpit. Again, during winters we see that the tip of our nose gets colder while other parts remain warm.

We check fever by touching the forehead, hand, and neck etc because those places are relatively warmer than other body parts.
