Okay there is just one more fact. The bulb, is formed by pumping air into melted metal, cooled and only then moved into space and then happens what happens. By the way the teacher says that the problem is solvable.
Bulb with volume of 5 liters is filled with nitrogen n = 3 molls. The bulb is set in space, the bulb cracks and the gas starts to expand. The nitrogen is considered as a real gas. Find the change in temperature. Joseph van der Waals' constant equals 0.137.
