A. expands unevenly between 0 ºC and 4 ºC
B. maintains fixed density
C. has high freezing point
D. wets glass
Correct Answer:
Option A = expands unevenly between 0 ºC and 4 ºC
Explanation
Water is most anomalous at low temperatures, with the remarkable density maximum at 4°C.
water is not used as thermometric liquid because it has low thermal expansivity,high specificc capacity and high vapour pressure.
