Question

A faulty thermometer has freezing points and
boiling point as 5°C and 95°C, What is the
correct value of temperature, if this thermometer
reaches 60°​

Answer 1

usually the thermometer fixed points basically are:

Lower point =0°c

Upper point=100°c

so in between there are 100 divisions.

each one division corresponds to 1°c

But in the above mentioned case :

Lower point=5°c

upper point=95°c

so total division=95-5=90

thus, 1 degree= 1 division=100/90

Now let us find the given temperature:

measured temperature 59 °c

=100x59/90

=65.56°c

hope it helps
