1. Take out a new sheet of paper and label it: Gas Law Problems #2 1. The pressure of a car tire is at 30 psi early in the morning when it is 0 ° C. In the middle of the day, when it is 30 ° C, you check the tire pressure again. What will it read? 2. The volume of a balloon is 300mL when I inflate the balloon at room temp (about 20 ° C). I take the balloon outside where it is 35 ° C. What will the new volume of the balloon be? 3. This room is at STP and is 10ft by 40ft by 25ft. If I run a vacuum and suck out a bunch air until the pressure drops to 0.8 atm, how much air have I taken away?

At 17 °C, a 0.80 mole sample of a gas exerts a pressure of 1.2 atmospheres. What is the volume of the container? 6. At what temperature (in Kelvin) would 4.0 moles of hydrogen gas in a 100 liter container exert a pressure of 1.00 atmospheres Ideal Gas Law Practice

3. 10. You go on vacation to Finland. You see a thermometer outside that says it is -40 °C outside. What temperature is it in degrees Fahrenheit? 7. How many moles of Oxygen gas do I have in 50 L pressurized container of 300 kPa that is at -70 0 C? 9. You and your best friend are astronauts at sea level on Earth in a rocket ship. The air in your brain has a volume of 500mL. You launch your rocket ship, but before you get to outer space, your friend wants some fresh air, so he/she opens a window on the ship. The high thermosphere outside has an atmospheric pressure of 0. 001 atms. What is the new volume of your brain? 8. 3 x 10 25 atoms of helium get put into a balloon. The room is about 65 degrees Fahrenheit. The balloon expands to 40 L. What is the pressure inside the balloon?
