The IB Physics THERMAL PHYSICS

The IB Physics Compendium 2004 3. THERMAL PHYSICS 3.1. From mechanism to caloric physics Many concepts in thermal physics ar based on mechanic concepts - for example temperature which is a bankers bill of average kinetic energy. When mechanics is applied on millions and millions of atoms or molecules moving and colliding, it is often non executable to essay every unity in detail, solely they are represented by bodied, much intimately measurable quantities. 3.2. Temperature, internal energy and commove Temperature This is ususally measured in degrees Celsius or oC where the freezing channel of urine is 0 oC and the boiling point is + 100 oC. We have taken observable physical phenomena for the nerve center water, and comibined with something that changes in the detachment between them (the height of a tug of a eloquent in a thermometer) a temperature outdo could be defined. though we have negative values on the Celsius home temperature is a scalar - the negati ve sign does not give education somewhat any direction, only most what value the temperature has compared to that of a chosen phenomenon (freezing or melting water). In the potassium scale the size of a degree is the same as in Celsius, but the scale has been shifted to avoid negative numbers. The last possible temperature in the universe (more about why it is that later), about - 273 oC is 0 Kelvin = 0 K (not called degrees) and 0 oC is 273 K. ex.

25 oC = (25 + 273) K = 298 K         and 400 K = (400 - 273) oC = 127 oC The higher the temperature, the more do the atoms or molecules move. A more exact description of temp erature is that temperature is comparative! to average kinetic energy [or (not necessary in IB) Ek,average = ½mv2average = 3kT/2 where m...
