Question

A faulty centigrade thermometer is examined. The upper and lower points are found to be 99.5°C and 0.5°C respectively. What is the correct temperature if this faulty thermometer reads 15.5?
a) 15.15°C
b) 16.16°C
c) 17.17°C
d) 18.18°C

Answer 1

If a thermometer is wrong calibrated then,

If X the temperature reading on the faulty thermometer scale then,

t= (UFP−LFP) (X−LFP) ×100 where, t=actual reading.

So, UFP=99.5°C,

LFP=0.5°C ,

For a faulty reading of X=15.5

the actual reading can be found by using above formula is =16.16°C

Answer 2

Answer:

15.15

Explanation:

(15.5-0.5/99.5-0.5)*100=15.15
