You fill a weather balloon with 10 moles of helium (He)gas. Consider that the gas will expand greatly as the balloon rises in the atmosphere and the pressure decreases. The balloon will expand to a completely full volume of 5000.0 Liters when the desired altitude is reached. Currently, the balloon is not at full volume because of the high atmospheric pressure at ground level. What is the pressure when the balloon rises to a point where the temperature is -10.0°C and the balloon has completely expaned to full volume, filled with the H2 gas?
