Eigentlich war nie ein "Teil 2" geplant, aber es hat sich noch einmal die Möglichkeit ergeben, sozusagen den Gegenpart zu filmen. Hier nun also das andere Ende der Berliner Straßenbahnlinie 61. Diesmal geht es vom S-Bahnhof Adlershof über Walther-Nernst-Str. und Magnussstr. zur Endhaltestelle Karl-Ziegler-Str. und wieder zurück. In der Wendeschleife ein paar Fotos vom Fahrzeug. Viel Spaß beim Zusehen :)
Este principio o ley cero, establece que existe una determinada propiedad denominada temperatura empírica θ, que es común para todos los estados de equilibrio termodinámico que se encuentren en equilibrio mutuo con uno dado. primera ley de la termodinámica: principio de conservación de la energía para la termodinámica, establece que si se realiza trabajo sobre un sistema o bien éste intercambia calor con otro, la energía interna del sistema cambiará. segunda ley de termodinámica: Esta ley marca la dirección en la que deben llevarse a cabo los procesos termodinámicos y, por lo tanto, la imposibilidad de que ocurran en el sentido contrario (por ejemplo, que una mancha de tinta dispersada en el agua pueda volver a concentrarse en un pequeño volumen). tercera ley de la termodinámica: El postulado de Nernst, llamado así por ser propuesto por Walther Nernst, afirma que es imposible alcanzar una temperatura igual al cero absoluto mediante un número finito de procesos físicos. Puede formularse también como que a medida que un sistema dado se aproxima al cero absoluto, su entropía tiende a un valor constante específico. (gracias por ver el vídeo)
우주 배경 복사의 발견은 빅뱅 이론에 대한 예측일까요? 많은 빅뱅 옹호론자들이 조지 가모프의 배경 온도 예측이 정확하다고 주장합니다. 하지만 이는 그 이전에 있었던 팽창하지 않는 우주 혹은 정적인 우주를 가정하고 했던 더 정확한 예측이 많이 있음을 간과하거나 숨긴 결과이며 또한 가모프는 초기 예측을 정정하고 1950년에는 10도 켈빈으로 1961년에는 50도 켈빈으로 예측 온도를 올렸음을 숨기고 하는 주장입니다. http://en.wikipedia.org/wiki/Cosmic_microwave_background 아래는 영상에 나온 각 온도 예측에 대한 Reference 입니다.

Use the Nernst equation to calculate cell voltage at non-standard conditions!
Nernst distribution law Instruments: -use the standard laboratory vessels and shaker Chemicals: -iodine solution in cyclohexane, cyclohexane, distilled water,starch solution, sodium thiosulfate Procedure: -mixtures of iodine in water and cyclohexane are already perscribed -mixtures are prepared in flasks with ground bottom -attach flasks in the shaker and shake 10-20 min, at room temperature,with a rate of 150 rpm -afterwards we put the content of flasks in separatory funnels -when layers are separated, the lower(aqueous) layer is dropped in a beaker while the top(organic) layer remains in separatory funnel -from the funnel or from the beaker we take aliquot for titration,taking care to avoid contamination by other solvent -an aliquot is taken so that consumption in titration is close to optimal 5-15 cm3 -aliquot is released in Erlenmeyer flask that contains ~25cm3 distilled water, 0,1 M KI and 2~3 cm3 starch solution -organic layer is titrated with 0,1M sodium thiosulfate to discoloration -when taking aliquots from the aqueous layer be careful to avoid contamination by other solvent -aqueous layer is titrated with 0,001M sodium thiosulfate to discoloration Result: -calculate the mean value of V(H2O)/cm3, V(organic solvent)/cm3, V(0,001M sodium thiosulfate), V(0,1M sodium thiosulfate) - calculate the concentration of iodine in water and cyclohexane c(I2)=V(Na2S2O3)*c(Na2S2O3)*1000]:[2*V(H2O/C6H12) ] log c(I2/H2O)= ----plotted on the x axis graph log c(I2/C6H12)= ----plotted on the y axis graph Intercept and slope should be determined using the least squares method. y=ax+b log K=b n=tg a(alpha)=a K is the number that tells us how many times the concentration of iodine in an organic solvent is higher than that in water, and the value of the exponent n indicates that the iodine dissociated in greater or lesser extent.

The Examiner 2013-07-09Walther Hermann Nernst FRS (25 June 1864 – 18 November 1941) was a German physical chemist and physicist who is known for his theories behind the calculation of chemical affinity as embodied in the third law of thermodynamics, for which he won the 1920 Nobel Prize in chemistry. Nernst helped establish the modern field of physical chemistry and contributed to electrochemistry, thermodynamics, solid state chemistry and photochemistry. He is also known for developing the Nernst equation.
Nernst was born in Briesen in West Prussia (now Wąbrzeźno, Poland) as son of Gustav Nernst, who was a country judge. Gustav died when Walther was only 24 years old. His mother was Polish and died when Nernst was young. Walther also had three older sisters and one younger brother. The third sister died due to cholera. Nernst went to elementary school at Graudentz. He studied physics and mathematics at the universities of Zürich, Berlin, Graz and Würzburg, where he graduated in 1887.
It was said that Nernst was mechanically minded in that he was always thinking of ways to apply new discoveries to industry. Nernst's hobbies included the pastimes of hunting and fishing.
