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, while the pressure is raised to 5.20 atm. What is the volume of the balloon in the liquid nitrogen?

Step 1
The formula to convert Celsius to Kelvin is K = °C + 273.15. So, the initial temperature T1 = 20°C + 273.15 = 293.15 K And the final temperature T2 = -196°C + 273.15 = 77.15 K We know the initial volume V1 = 4.91 L and the initial pressure P1 = 1.00 atm. The Show more…

$\bullet$ The gas inside a balloon will always have a pressure nearly equal to atmospheric pressure, since that is the pressure applied to the outside of the balloon. You fill a balloon with helium (a nearly ideal gas) to a volume of 0.600 L at a temperature of $19.0^{\circ} \mathrm{C}$ . What is the volume of the balloon if you cool it to the boiling point of liquid nitrogen $(77.3 \mathrm{K})$ ?
