A helium balloon is filled with volume of 2.88×10 cubed liters at 722 mm Hg and 19°C. When the balloon is released it rises to an altitude where the pressure and temperature or 339 mm HG and -55°C respectively. What is the volume of the balloon in liters?

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
