  2. What is relationship between volume and pressure according to Boyle’s law? Draw the correct graph. Indirect, as pressure increases volume will decrease. P V 1 - $100

  3. 1 - $200 A gas occupies 12.3L of space at a pressure of 0.75 atm. What will its new pressure be if the gas is compressed to 5L of space? • 12.3(0.75) = X(5) • 1.845 atms

  4. 1 - $300 • A gas in a sealed container has a volume of 1.25L and pressure of 2.0 atm, what would the pressure be if the volume was increased to 5.00 L. • 1.25(2) = 5.00(X) • .5 atm

  5. 1 - $400 • An .085 L container is filled with gas until the pressure reaches 5.92 atm. If the pressure is decreased to 3.05 atm, what is the new volume inside the container? • .165 L

  6. 1 - $500 • If 5.6 liters of gas is in a piston, at a pressure of 1.5 atm and the gas is compressed to a volume of 4800 milliters, what would the pressure inside the piston be? • 1.7 atm

  7. 2 - $100 • What happens to the pressure of a gas as temperature increases? What type of relationship is this? • As temperature increases, the volume will also increase. • Direct

  8. 2 - $200 • A balloon has volume of 5L at a temperature of 310 K. If the balloon is cooled down to 200 K, what will its new volume be? • 5/310 = X/200 • 3 liters

  9. 2 - $300 • A 0.6477 L balloon is in a room at 310. K is exposed to an increase in temperature. What is the new temperature in the room if the volume of the balloon increased to 0.7555 L? • 362 K

  10. 2 - $400 • Oxygen gas is at a temperature of 40.0OC when it occupies a volume of 2.30 L. To what temperature should it be raised to occupy a volume of 6.50 L? • 885 K

  11. 2 - $500 • A canister of hairspray has a pressure of 405.2 kPa when it’s at room temperature (300.0 K). If it is thrown into a fire where the temperature goes up to 773.0 K just before it explodes, calculate the pressure inside the container in mmHg. • 7833 mmHg

  12. P1V1 n1T1 P2V2 n2T2 = 3 - $100 • Write the Combined Gas law.

  15. 3 - $400 A container whose lid slides up and down contains a sample of gas that has a volume of 4.0 liters at 25oC and 1.0 atmosphere. The gas is heated to 310 K, the pressure is held at 2.0 atmosphere. What is the final volume of the gas? • 2.1 L

  16. 3 - $500 • A canister is filled with 10.0L of compressed gas at STP. If the temperature is raised to 200OC and the canister can expand to 12.5 L, find the new pressure. • 1.39 L

  17. 4 - $100 • What is the equation for Ideal Gas Law? When should this equation be used? • PV=nRT • When there is not a second P, V, or T.

  18. 4 - $200 16 L of carbon dioxide is at a temperature of 45º C and a pressure of 85 kPa. Calculate the number of moles of gas present. • 85(16) = n (8.31)(45+273) • .51 moles
