Must be calculated Temperature inside and outside The air temperature that day was around 13 degrees C Temperature needs to be at least 100 degrees C inside the tanker because that is the boiling point of water. We will presume the temperature was 120 degrees C Volume and how the volume changes. Initial volume (capacity of train car) was 78,244 L Volume ration of gas H2o to liquid is 820 times Moles inside tanker Unknown number of moles but it is constant because it is a closed system after the steam was pumped in, and remained so. Type of metal the train car is made out of What was inside the tanker before the implosion Was it gas inside the train car?= Yes, at the beginning the tanker was filled with 100% steam molecules. Protocol of the train car, how long was the steam in the tanker Was it a closed or open system?= Closed after the steam was pumped in. Because for a period of time it was an open system, it retains the outside pressure in the beginning (1 atm) Using these numbers and PV=nRT, we can calculate all the numbers. Before calculating the numbers, Celsius must be converted to Kevin for a correct number. P1= 1 atm, because it was an open system at first V1= Initial volume, 78,244 L T1= 13 degrees C outside, 120 degrees C inside (Since PV=nRT is applied to the inside of the tanker this time, we will use the number 120 C) P2= 0.728 atm V2= 78,244 L T2= 13 C (lowest possible temperature therefore most extreme scenario temperature wise. Because of this, the number is not going to be exact, as we do not know for certain the temperature) P3= 1 atm V3= 56,961.632 L (Rounded to 56,962 L in the visual) T3= 13 degrees C because once the system is open when it is collapsed, once it's open it will become the same temperature as the outside (Which is 13 degrees C) I recognize that the end pressure is not certainly 1 atm because although the pressure must be balanced enough for the tanker to not continue to implode, the balance is not necessarily perfect and often times it isn't so. In addition, I am calculating the during temperature to be 13 degrees C which is the lowest the tanker could be cooled to. This is indeed the most extreme situation but it cannot be certain. Furthermore, the numbers for atmosphere and the temperature of the steam were all assumed, therefore more likely than not, this is incorrect to the actual situation.
