e number of B. T. U. required to change i Ib. ofice at 32° F. to i Ib. of water at 32° F., that is, to find the latent heat ofice. Method. Weigh out 5 Ib. of water in a pail and warm it to about 80° F. Take its temperature.Pour into it i Ib. ofdry powdered ice orsnow. Stir and take theresulting… … HEAT CAPACITY, SPECIFIC HEAT, LATENT HEAT 129 Example, i Ib. of ice at 32° F. is mixed with 5 Ib. of water at 80° F.rand the resulting temperature 1548° F. What is the latent heat of ice? The 5 Ib. of water is cooled from 80° F. to 48° F., that is, through 32°.Therefore it gave up 5 X 32 = 160 B.T.…
