A helium-filled balloon has a volume of 2.48 L and a pressure of 150 kPa. The volume of the balloon increases to 2.98 L after you climb up a very steep mountain with this balloon. (Temperature is kept constant). Be sure to answer both parts A and B. A. What is the new pressure of the helium gas? (For full credit, write the appropriate gas law formula, list the givens in the problem, indicate what the unknown is, and give your calculated answer). B. Use the kinetic molecular theory to explain why the volume of the gas changed in this scenario.
