Propane can maintain a liquid state at any temperature, because temperature alone does not dictate what state it maintains. One must also take into account PRESSURE. The temperatures you provided are at 1 atmosphere. If we assume that you mean 1 atmosphere, then propane will remain liquid between -189.9 C and -42.1 C. The temperature at which propane “dissipates” (notice spelling) is undefined because “dissipate” is not clearly defined. That is not a scientific term. If propane is properly maintained within a tank, then it does not dissipate at any temperature because it IS contained. If you break open the tank and the outside temperature is less than -42.1 C then the liquid will just pour out onto the ground. Is this dissipating??? If you break open the container at temperatures well above -42.1C, then the propane will rapidly boil and become gaseous. Is this dissipation??? You see, your questions are as ignorant as you are.
