A balloon filled with helium gas at 20 °C occupies 4.91 L at 1.00 atm.The balloon is immersed in liquid nitrogen at -196°C,raising the pressure to 5.20 atm.What is the volume of the balloon in the liquid nitrogen?
A)0)25 L
B)3)6 L
C)6)7 L
D)97 L

Using the combined gas law, (P1V1/T1) = (P2V2/T2), where T is in Kelvin, we can solve for V2. Converting temperatures to Kelvin, T1 = 293 K and T2 = 77 K. Substituting the values, (1.00 atm * 4.91 L / 293 K) = (5.20 atm * V2 / 77 K), solving for V2 gives approximately 0.25 L.
