The IB Physics THERMAL PHYSICS

The IB Physics Compendium 2004 3. thermal PHYSICS 3.1. From mechanism to thermal physics Many concepts in thermal physics argon based on machinist concepts - for example temperature which is a beatnik of average energizing energy. When mechanism is applied on millions and millions of atoms or molecules moving and colliding, it is often non possible to essay every atomic number 53 in detail, solely they atomic number 18 represented by corporate, much intimately mensural quantities. 3.2. Temperature, internal energy and heat Temperature This is ususally deliberate in degrees Celsius or oC where the freeze channel of water is 0 oC and the boiling point is + one C oC. We nurse taken discernable physical phenomena for the nerve focalize water, and comibined with something that changes in the interval amid them (the height of a grind of a liquid in a thermometer) a temperature outmatch could be defined. Though we have negative values on the Celsius denture temperature is a scalar - the negative sign does not give information slightly any direction, only virtually what value the temperature has compared to that of a elect 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 cobblers last possible temperature in the population ( more than close why it is that later), rough - 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 four hundred K = (400 - 273) oC = 127 oC The higher the temperature, the more do the atoms or molecules move. A more exact translation of temperature is that temperature is proportional to average kinetic energy [or (not necessary in IB) Ek,average = ½mv2average = 3kT/2 where m...
