  1. You need a calculator, reference tables, and paper with a pen now. 54 Gas Problemshandout coming soon. Do not copy the questions, write a formula every time!

  2. 3. The pressure on 200. liters of xenon is decreased at constant temperature from 130. kPa to 120. kPa, what is the new volume of xenon in liters? Don’t sweat it, this is not you!

  3. P1V1 = P2V2 (130. kPa)(200. L) = (120. kPa)(V2) 217 Liters = V2 It’s me!

  4. 4. The pressure on 150 milliliters of nitrogen gas at constant temperature is changed from 50.65 kPa to 101.3 kPa. What is the new volume of nitrogen? At your table you should be dancing now,this is so easy!

  5. P1V1 = P2V2 (50.65 kPa)(150 mL) = (101.3 kPa)(V2) 75 milliliters = V2 Dance like no one is watching!

  6. 5. A 114.5 liter sample of oxygen gas is held at standard temperature while the pressure is changed from normal to just 560. mm of Hg. What is the new volume in liters? Calvin & Hobbes challenge you to get this right!

  7. P1V1 = P2V2 (760. mm Hg)(114.5 L) = (560. mm Hg)(V2) 155 Liters = V2 Calvin & Hobbes say thanks for working hard!

  8. 12. At constant pressure, 205 mL of argon gas is at 10.0°C is heated to 27.0°C. The new volume of the gas is how many mL? Inside Charley’s hat there is a gas, called air, under pressure. When the heat from his head warms it, the balloons pressure will ????

  9. V1 = V2 T1 T2 205 mL = V2 283 K 300 K (283)V2 = 61500 V2 = 217 mL Temperature and pressure are directly proportional. If the heat goes up, so does the pressure!

  10. 21. The particle diagram below represents a sample of gas sealed in a 1.0 liter flask. The sample was heated gently and the pressure measured over a range of temperatures as reported in the data table. In a full sentence, state the relationship between temperature and pressure of a gas when the volume remains constant.

  11. Temperature and pressure are directly proportional. As this gas heats up, the pressure increases, because, with more kinetic energy, the particles have stronger collisions, and they have more collisions. Both lead to higher pressure.

  12. 41. What pressure, in atm, is equal to 152 kPa? A. 1.50 atm B. 1.00 atm C. 0.670 atm D. 2.00 atm Why does heating the air in the balloon make the balloon go up? Have you ever taken a hot air balloon ride?

  13. 41. What pressure, in atm, is equal to 152 kPa? A. 1.50 atm 1.0 atm101.3 kPa 152 kPa1 X = 1.50 atm Hotter air (increased temp) makes the particles move further apart, lowering density. Low density floats in normal air density
