The coefficient of thermal expansion is defined by
the coefficient of thermal expansion in Eq. (1.2-15)
is used for gases and liquids.
The coefficient of thermal expansion is an intensive
quantity and is usually positive.
That is, if the temperature is raised the volume
usually increases.
There are a few systems with negative values of
the coefficient of thermal expansion. For
example, liquid water has a negative value of α
between 0 ◦ C and 3.98 ◦ C. In this range of
temperature the volume of a sample of water
decreases if the temperature is raised.
