6. Book Problem A gas occupies 3.8 L at 0.70 atm pressure. If we expand the volume at constant temperature to 6.5L, what is the final pressure? A gas is expanded from an initial volume of 20.5 L at 0.92 atm at room temperature (298 K) to a final volume of 340.6 L. During the expansion the gas cools to 12.0 °C. What is the new pressure?

7. How Do Hot Air Balloons Work

8. The air inside the balloon is heated The air molecules move faster They hit into each other with more force This force forces some molecules out of the balloon This means there is less air inside the balloon Because there is less air, the inside is less dense Because it is less dense, the balloon will rise
