Question

A thermometer is graduated in millimeters. It registers – 3 mm when the bulb of thermometer is in pure melting ice and 22 mm when the thermometer is in steam at a pressure of 1 atmosphere. The temperature in oC when the thermometer registers 13 mm is:

Solution

Correct option is

 

22 – (– 3) = 25 mm length corresponds to an interval of 100oC.

So  [13 – (–3)] = 16 mm length corresponds to
