, as the temperature rises further, it begins to expand, andcontinues to expand until the boiling point is reached. At thetemperature of 8° C, the water has attained practically the samevolume it had at 0° C. This is shown in Fig. 160, where thevertical distances represent the changes in the volume… … As a mass of water in a river or lake is cooled from ordinarytemperatures down to 0° C, it contracts and becomes denseruntil the temperature of 4° C. is reached, at which point it at-tains its maximum density. Thisdenser, colder water, there-fore, sinks to the bottom, andwarmer, lighter water takes…
