  1. Also, does anyone know if the distance between the carbon atoms in a C60 molecule are all exactly the same distance apart or do they vary (since there's pentagons and hexagons in its structure)?
  2. Does anyone have any idea of what the volume of C60 bucky ball is?
  3. If classical thermodynamics deals with macro states, why do we care how the heat transfer occurs? My understanding suggests that how the heat is transferred is irrelevant? All we care about are the final states of the systems after an equilibrium is reached? If we're not at equilibrium then we simply wait for equilibrium to occur. Why make the distinction?
  4. If we take a gas thermometer and cool it to absolute zero, the pressure vanishes. What happens to volume? The way I see it, it can't be zero, however on a PV vs T graph, 0 x V = 0 so volume can be anything but at the end of the day the 0 pressure multiplies by volume and yields 0. So, here's where the algebra comes in that I'm getting confused over... Comparing two gas thermometers (one much larger than another) both initially at room temp... the first one is of a volume of 1m^3 and is argon and another one we have equaling to 5cm^3 and is helium. Then they are both cooled. At some point your pressure goes to zero, whatever that means because how do you even measure the pressure of these gasses at such low temps (in fact this is the third question), then we get PV = 0 for both thermometers but how are you sure that both are at the same temperature if we're looking at two very differently sized cubes? So the first question is 0 x X = 0 and 0 x Y = 0 the volumes are non zero for both yet the formula suggests they are zero??? The second question is... how do you know temperature stops going any lower just because the volume seemingly stops to decrease? Third question is, how do you measure such pressures?
