A volume of 2 L of helium at 46'C and 1.2 atm pressure was added to a vessel that contained 4.5 L of nitrogen at STP. What is the total pressure and the partial pressure of each gas at STP after helium is added?
The answer to this problem is P = 1.46 atm, P helium = 0.46 atm, P nitrogen = 1.00 atm. However, when I tried to use the Combined Gas Law, why must V2 be the volume of N2? Does adding H2 to N2 not change the volume inside the vessel? Can sb please explain in detail? I am having troubles applying Gas Laws. Thank you very much!

A helium-filled balloon at 1.00 atm pressure has a volume of 1.200 L. It is placed in a freezer and its volume decreases, stopping at 1.010 L. (Assume that the static internal and external pressures are equal, that the balloon contains only helium, and helium behaves as an ideal gas.) Calculate ΔE for the gas in the balloon.
