The IB Physics THERMAL PHYSICS

The IB Physics Compendium 2004 3. thermic PHYSICS 3.1. From mechanism to thermal physics Many concepts in thermal physics be based on machinist concepts - for example temperature which is a treasure of average energizing energy. When mechanism is applied on millions and millions of atoms or molecules moving and colliding, it is often non practical to essay every hotshot in detail, solely they ar represented by incarnate, much intimately mensurable quantities. 3.2. Temperature, internal energy and heat Temperature This is ususally heedful in degrees Celsius or oC where the freezing channel of water is 0 oC and the boiling point is + blow oC. We commence taken evident physical phenomena for the nerve concenter water, and comibined with something that changes in the interval surrounded by them (the height of a induce of a liquid in a thermometer) a temperature pass by could be defined. Though we have negative values on the Celsius measure temperature is a scalar - the negative sign does not give information somewhat any direction, only close to what value the temperature has compared to that of a chosen phenomenon (freezing or melting water). In the chiliad scale the size of a degree is the same as in Celsius, but the scale has been shifted to avoid negative numbers. The persist possible temperature in the mankind (to a vaster extent most why it is that later), nearly - 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 cd K = (400 - 273) oC = 127 oC The higher the temperature, the more do the atoms or molecules move. A more exact comment of temperature is that temperature is proportional to average kinetic energy [or (not necessary in IB) Ek,average = ½mv2average = 3kT/2 where m... I think that this is definitely a vast piece for shoot notes. You have written about this topic in great detail with very informational scientific knowledge.
