A very flexible helium-filled balloon is released from the ground into the air at 20. ∘ C . The initial volume of the balloon is 5.00 L , and the pressure is 760. mmHg . The balloon ascends to an altitude of 20 km , where the pressure is 76.0 mmHg and the temperature is − 50. ∘ C . What is the new volume, V 2 , of the balloon in liters, assuming it doesn't break or leak?
