(c) the variation of the resistance of a wire with
temperature
(d) All of the above
more sensitive than the​

Answer 1

Answer:Volume As Thermometric Property

Explaining **

Mercury does not wet glass or cling to it, and this property, coupled with its uniform volume expansion throughout its liquid range, makes it useful in liquid-in-glass thermometers. Gases such as nitrogen or simply air are also suitable substances for use in volumetric gas thermometers.
