Question

A faulty thermometer has its fixed points marked 5 c and 95 c . the temperature of a body is measured by faulty thermometer is 59 c ,find the correct temperature of the body on the celsius scale . ( 3 marks question )

Answer 1

Dear student:

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 is clear.

Answer 2

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°    I HOPE THIS HELPS YOU
