|
|
Go to: http://www.physlink.com/Education/AskExperts/ae518.cfm Boyle's Law describes the relationship between what two variables? Write the formula for Boyle's Law. How does a bicycle pump exemplify Boyle's? |
|
Go to http://www.grc.nasa.gov/WWW/K-12/airplane/aboyle.html Sketch the graph of Boyle's Law. |
|
Go to http://www.1728.com/boyle.htm scroll down and use the Boyle's Law calculator to solve. If a gas fills 22.40 Liters at 760.0 torr, how many Liters will the gas occupy at 800.0 torr? What is the pressure in atm of 20.0 mL of CO2 if 100.0 mL has a pressure of 1.00 atm? |

Go to: http://dbhs.wvusd.k12.ca.us/webdocs/GasLaw/Gas-Charles.html With which gases did Charles experiment? What did Charles discover about thess gases? When doing Charles Law calculations, what must be done to temperature? What is the formula for Charles Law? |
|
|
|
Go to: http://www.1728.com/charles.htm scroll down and solve using the calculator. If 150. mL of oxygen has a temperature of 25°C, what will the volume be at -10 °C? What is the temperature in Celsius if 500. mL of gas at 37°C cools to occupy a volume of 100. mL? |
|
|
|
Go to: http://www.grc.nasa.gov/WWW/K-12/airplane/aglussac.html Sketch graphs of Charles Law and Gay-Lussac's Law. What factors are constant in Charles Law? |

Gay-Lussac's Law |
image from: http://dbhs.wvusd.k12.ca.us/webdocs/GasLaw/Gas-Charles.html
|
Go to: http://dbhs.wvusd.k12.ca.us/webdocs/GasLaw/Gas-Gay-Lussac.html What is the relationship between the pressure and the Kelvin temperaure of a gas? What factors are held constant? Write the formula for Gay-Lussac's Law. |
|
|
|
Go to: http://www.1728.com/gaspres.htm scroll down and calculate: If a container of hydrogen at 300. K and 38000 mm Hg pressure is heated to 3010. K, what will be the new pressure in mm Hg? If the conatiner can withstand a pressure of 380000 mm, what do you think will happen to this container when heated to 3010. K? |

Combined Gas Law |
|
Go to: http://www.fordhamprep.org/gcurran/sho/sho/lessons/lesson76.htm Write the formula for the combined gas law to solve for volume. Why is it appropriate to use the combined gas law?
|
|
Go to: http://www.1728.com/combined.htm scroll down and calculate. Nitrogen occupies a volume of 250. mL at 25°C and 103 kPa. What volume in mL would the gas occupy at 0°C and 96.0 kPa? |

|
Go to: http://dbhs.wvusd.k12.ca.us/webdocs/GasLaw/Gas-Dalton.html Write Dalton's Law of Partial Pressures for a mixture of Helium and Neon. Write Dalton's Law of Partial Pressure for finding the total pressure of gases in a mixture. Where is Dalton's Law most commonly used? In our calculations, how do we get rid of the pressure attributed to water? Calculate: If 45.0 mL of Hydrogen at 295 K and 763 mm Hg pressure is collected over water, what would be the volume in mL of the dry gas at 273 K and 800.mm Hg pressure. (The vapor pressure of water at 22°C is 19.8 mm). |
