Behavior of gases

• What are the four gas laws?

  Boyle's Law, Charles's Law, Gay-Lussac's Law, Combined law
• What is boyle's law?

  when the volume decreases as the pressure increased,vice versa
• What formula is used when you convert Celsius to Kelvin?

  Celsuis + 273.15 = K
• Describe gas

  Have no definite shape and volume
• What are the properties of gas?

  • Volume
  • Pressure
  • Temperature
  • Amount
• What is Charle's Law?

  directly proportional to the Kelvin (K) temperature.
• What is the General Formula?

  P1V1 = P2V2
• What is the general formula of Charle's Law?

  V2T1 = V1T2
• Charle's Law

  The temperature decreases, the volume also decreases
• Describe Gay lussac's law

  When the volume and amount of gas is constant, pressure and temperature are directly proportional.
• Gay lussac's law

  P1T1 = P2T2
• A 2.50-L volume of hydrogen measured at –196 °C is warmed to 100 °C. Calculate the volume of the gas at the higher temperature, assuming no change in pressure.

  12.1 L
• A balloon that is 100.21 L at 21 °C and 0.981 atm is released and just barely clears the top of Mount Crumpet in British Columbia. If the final volume of the balloon is 144.53 L at a temperature of 5.24 °C, what is the pressure experienced by the balloon as it clears Mount Crumpet?

  0.644 atm
• A gas occupies 12.3 liters at a pressure of 40.0 mmHg. What is the volume when the pressure is increased to 60.0 mmHg?

  8.20 L
• A gas occupies 11.2 liters at 0.860 atm. What is the pressure if the volume becomes 15.0 L?

  0.642 atm
• 600.0 mL of air is at 20.0 °C. What is the volume at 60.0 °C?

  682 mL
•  A gas occupies 900.0 mL at a temperature of 27.0 °C. What is the volume at 132.0 °C?

  1215 mL
• A gas occupies 1.00 L at standard temperature. What is the volume at 333.0 °C?

  2.22 L
• At 225.0 °C a gas has a volume of 400.0 mL. What is the volume of this gas at 127.0 °C?

  321 mL
• If a gas is cooled from 323.0 K to 273.15 K and the volume is kept constant what final pressure would result if the original pressure was 750.0 mmHg?

  634.2 mmHg
•  A gas has a pressure of 0.370 atm at 50.0 °C. What is the pressure at standard temperature?

  0.313 atm
