       The notion of temperature is fundamental to the consideration of all heat problems.
Temperature is a measure of the degree of hotness or coldness of a body. Temperature is
measured by means of a thermometer depends upon the fact that most solids and liquids
expand as their temperature rises. There are one or two exceptions. There is, for instance, a
kind of steel called invar which doesn’t change its dimensions as temperature changes.
Another exception is that very odd liquid water, which has many strange properties. As water
gets colder it contracts, which is ordinary behaviour, until it reaches the temperature of 4C,
above freezing-point. After that, as it gets colder, it expands.
