Many
students lack even a basic perception of the meaning of
hypothesis and of the fact that the presence of a hypothesis
implies the statement of some consequences, and they fail to
identify the next pieces of information (the entropy of all
substances, whether elements or compounds, is always
positive; at 0 K, the entropy of a substance may be zero, and it
is zero if the substance is in the state of a perfect crystal) as
consequences of the initial hypothesis. An in-class interactive
analysis of the sentence elucidating all the logical connections
typically requires at least 20-30 minutes.
