### Consider the following data that show temperature of a 1,000 g sample of water at normal atmospheric pressure as a function of heat supplied.

Water is the most important substance on Earth. One reason for its usefulness is that it exists as a liquid over a wide range of temperatures. In its liquid range, water absorbs or releases heat directly in proportion to its change in temperature. Consider the following data that show temperature of a 1,000 g sample of water
