10. A balloon has a volume of 0.5 L at 20°C. What will the volume be if the balloon is heated to 150°C? Assume constant pressure and mass.
7. A helium balloon has a pressure of 40 psi at 20°C. What will the pressure be at 40°C? Assume constant volume and mass.
1. Boyles law states that if you squeeze a fixed amount of a gas into a smaller volume, the pressure will increase. Explain why in your own words.
3. Atmospheric pressure at the top of Mt. Everest is about 150 mm Hg. That is why climbers always bring oxygen tanks. If a climber carries a 12.0 liter tank with a pressure of 35,000 mm Hg, what volume will the gas occupy if it is released at the top of Mt. Everest?
The atmospheres of Mars and Venus are mostly carbon dioxide. Earths atmosphere contains only a fraction of a percent of carbon dioxide. Why is Earths atmosphere so different from those of Mars and Venus?
