Water is unsuitable for use as a thermometric liquid because it
A
expands unevenly between 0oC and 40oC
B
has narrow temperature range
C
has a concave meniscus
D
maintains a fixed density
Verified Correct Answer: B.
Physical Principles & Numerical Solution
Water's freezing point is 0^\circC and its boiling point is 100^\circC at standard atmospheric pressure, which provides a limited temperature range for measurement compared to other liquids used in thermometers. Other liquids like mercury can measure a wider range of temperatures.
