Example. . 4 Ib. of iron at 212° F. placed in 5 Ib. of water at 55° F.warms… … FIG. 88. — Measuring the heat capacity of iron. 12°, therefore the water received 5 X 12 = 60 B.T.U. This heatcame from the iron. The 4 Ib. of iron cooled from 212° F. to 67° F., or through 145° F.,therefore we can say: 4 Ib. of iron in cooling 145° gave up 60 B. T. U. i Ib. of iron in cooling 145°…
