Problem 1.7 – 1.12 from Thermal Physics by Daniel Schroeder I need the solution for the 2 problem. see attached picture filesProblem 1.7, part (a) only, from Thermal Physics by Daniel Schroeder (the key word here is estimate – don’t look up what the size of the bulb of a thermometer is, just take a reasonable guess. You don’t even have to have one to look at. Estimating is a key skill in physics; students often get hung up on trying to find the “accurate” answer. The best advice: “Dare to be Imprecise”!)Problem 1.12 from Thermal Physics by Daniel Schroeder (the average distance apart of molecules of air). Problem 1.12. Calculate the average volume per molecule for an ideal gas at
room temperature and atmospheric pressure. Then take the cube root to get
an estimate of the average distance between molecules. How does this distance
compare to the size of a small molecule like N2 or H2O?

Problem 1.7) When the temperature of liquid mercury increases by one degree
Celsius for one kelvin), its volume increases by one part in 5500. The fractional
increase in volume per unit change in temperature (when the pressure is held fixed)
is called the thermal expansion coefficient, B:
AV/V
BE
AT
(where V is volume, T is temperature, and A signifies a change, which in this
case should really be infinitesimal if ß is to be well defined). So for mercury,
B = 1/5500 K-1 = 1.81 x 10-4 K-1. (The exact value varies with temperature,
but between 0°C and 200°C the variation is less than 1%.)
(a) Get a mercury thermometer, estimate the size of the bulb at the bottom,
and then estimate what the inside diameter of the tube has to be in order for
the thermometer to work as required. Assume that the thermal expansion
of the glass is negligible.
