# Problem: A sealed balloon is filled with 1.00 L helium at 23°C and 1.00 atm. The balloon rises to a point in the atmosphere wherethe pressure is 220. torr and the temperature is -31°C. What is the change in volume of the balloon as it ascends from1.00 atm to a pressure of 220. torr?

###### FREE Expert Solution

We are looking for the change in volume and to solve that we would need initial and final values for volume. We are only given the initial volume so we'd have to solve for the final Volume first.
