I need the solution for the 2 problem. see attached picture files
Problem 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).
