Biological importance of the anomalous expansion of water

Biological importance of the anomalous expansion of water The peculiar expansion of water has an important bearing on the preservation of aquatic life during very cold weather (Fig. 15.15). As the temperature of a pond or lake falls, the water contracts, becomes denser and sinks. A circulation is thus set up until all the water reaches its maximum …

To compare the expansions of various liquids

To compare the expansions of various liquids Different liquids have different thermal expansions. To demonstrate this, several fairly large glass bulbs with glass stems are filled to a short distance above the bulb with various liquids (Fig. 15.12). In order to make a fair comparison, the bulbs and stems must all be of the same size. The bulbs …
