Physics Question on thermal properties of matter
If boiling point of water is 95∘F, what will be reduction at celsius scale?
A
7∘C
B
65∘C
C
63∘ C
D
35∘C
Answer
35∘C
Explanation
Solution
The relation between Celsius scale and Fahrenheit scale is as derived below:
100 parts of Celsius scale =180 parts of Fahrenheit scale
∴ 1 part of Celsius scale
=59 parts of Fahrenheit scale Hence, TF=32+59TC Or TC=95(TF−32)
Given, TF=95oF
∴ TC=95(95−32)
=35oC
