A balloon filled with helium gas at 20°C occupies 5.91 L at 1.00 atm.The balloon is immersed in liquid nitrogen at -196°C,while the pressure is raised to 5.20 atm.What is the volume of the balloon in the liquid nitrogen?

Using the combined gas law:
(P1V1/T1) = (P2V2/T2)
where P1=1.00 atm, V1=5.91 L, T1=20°C+273.15=293.15 K, P2=5.20 atm, T2=-196°C+273.15=77.15 K.

Solving for V2:
V2 = (P1V1T2)/(P2T1) = (1.00 atm)(5.91 L)(77.15 K)/((5.20 atm)(293.15 K)) = 0.30 L.

Therefore, the answer is A) 0.30 L.
