Not illustrated. 1910 Excerpt: ...at K, we have (1) p + H d2g--l2d3g = p + H d1g--lld3g, where p is the atmospheric pressure and g is the acceleration due to gravity. If j8 is the coefficient of cubical expansion of the liquid, referred to the volume at oC, d0 its density at oC, V0 the volume of a given mass m of it at oC, and V1 the volume of the same mass at f1C, we have V1 = V0 (1 + 8 tl). Since V0 = m/d0 and Vl = m/dl, it follows by substitution that d0 = rfj (1 + p tl). This is true generally, and therefore in the present experiment. Hence (2) da-dl (I + p t, ), (3) d0 = d2 (1 + p t2), (4) do = da (1 +Pt, ). Substituting in (1) the values of dl, d2 and d3 obtained from (2), (3) and (4) and simplifying, we get H h H H-+1+ Pt, 1 + " Clearing of fractions and putting the equation into the form a/32 + bp + c--o, we get by solution a--b /--4-c P Ta' where a =--H tl t3 + h tl t2--H t2 t3, bH (t. + t, ) +h (tl + t2)-H (t2 + ts), and By measuring the lengths H, h and the three temperatures tL, t2, ta, the value of fi may at once be calculated. (a) Pass cold running water through the jacket M and steam through L, keeping thermometers on the two sides. Instead of running water, it may be necessary to use a bath of ice and water in M. Wrap a cloth about the horizontal tube A'E, and keep this wet with cold water to make the conduction of heat to the column GB as small as possible. Note the difference in height of the menisci at G and K when the temperatures become steady. The distance h must be very accurately determined at each setting, whereas a moderately accurate reading of the height H is sufficient. Do not forget to take simultaneous readings of the heights and the temperatures. Continue the experiment long enough to be certain that the conditions are steady. (b) Calculate the ...
