February 20, 2012 University Physics, Chapter 17 1 Chapter Chapter 17: Temperature 17: Temperature This is a concept we all understand from experience Some examples include weather forecasts of the air temperature, doctors  indicating body temperature, or the personal determination of whether an object  is hot or cold Thermal equilibrium  is reached when a hot object in contact with a cool one  eventually have the same temperature because the hot object cools and the cool  object warms up Hot Cold Hot Cold Warm Warm

Temperature Temperature Heat  is the transfer of a type of energy sometimes called  thermal  energy It is in the form of random motion of the atoms and molecules  making up the matter being studied Temperature  is directly related to the tendency of the object to  transfer heat Heat is always transferred from a hotter object to a cooler one February 20, 2012 University Physics, Chapter 17 2

Measuring Temperature Measuring Temperature Measuring temperature relies on the fact that if 2 objects are in  thermal equilibrium with a third object, they must be in thermal
