Homework Statement
For the construction of a thermometer, one of the essential requirements is a thermometric substance which
a. remains liquid over the entire range of temperature to be measured
b. has a property that varies linearly with temperature
c. has a property that varies with temperature
d. obey Boyle's Law
e. has a constant expansivity
Homework Equations
The Attempt at a Solution
I think the answer can be (a) and (b). The substance must remains liquid so that it can measure the temperature and it must varies linearly with temperature to obtain good measurement. But the answer can be only 1...I don't know how to choose the right one
Thanks
