TEXT
1. GENERAL
Temperature. How hot is hot? Don't try to answer this question now; it will probably
drive you crazy---- and we want you to be sane while studying this subcourse.
Although we can't tell you how hot is hot, we do know we can measure the "hotness" of
an object by determining its temperature. Temperature means intensity of heat. In other
words, temperature may be defined as-- the condition of a body which determines the
transfer of heat to or from other bodies. If you prefer a more technical definition--the
absolute temperature of a body is proportional to the average kinetic energy of the
molecules of which the body is composed. Now, before we get too confusing----what is
actually measured when the temperature of an object is determined?
Basically, temperature means intensity of heat, and may be defined as an arbitrary scale.
Temperature is only relative and is difficult to define in terms of simplest concepts.
2. There are many temperature measuring devices. One such device is the Air
Thermometer. Galileo is credited with the development of an air thermometer in 1593.
