# What is the change in its thermodynamic temperature?

A thermometer has a quartz body within which is sealed a total volume of 0.410 cm3 of mercury. The stem contains a cylindrical hole with a bore diameter of 0.10 mm. How far does the mercury column extend in the process of rising from 10°C to 86°C? Neglect any change in volume of the quartz.

I know how to do this problem, using V=V0(1+B*delta t). I just cannot find the expansion coefficient. can anyone help me out? ive been searching on the web for 15 minutes and i keep finding physics labs and crap, but no tables with values for expansion coefficients.

I dont have the text book for my class which has all the values in it so im kinda SOL.

A block of steel is heated from 10F to 110F. What is the change in its thermodynamic temperature?

Is this one as simple as i think it is? Is the answer just 100? that seems way to easy to me but i dont see what else it would be asking.

Consider this - http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/thexp2.html#c3

Thermal expansion coefficient of mercury is 182 x 10-6/ºC at 20ºC

Density of Hg at 300K = 13529 kg/m3, and density at 350K = 13407 kg/3.

Data from F. Incropera and D. De Witt, "Fundamentals of Heat Transfer", John Wiley & Sons, 1981, Table A.5, "Thermophysical Properties of Saturated Liquids."

CRC Handbook of Chemistry and Physics should also have these data.
