1. Take out a new sheet of paper to turn in today. Number it 0 to 12 and leave lots of space between problems. Label it Gas Law Practice Problem 0: What is A, B, and C in this graph? What do we call this graph?

2. 1)The temperature inside my refrigerator is about 5 ° Celsius. If I place a balloon in my fridge that initially has a temperature of 25 ° C and a volume of 0.5 liters, what will be the volume of the balloon when it is fully cooled by my refrigerator? 2)A man heats a balloon in the oven. If the balloon initially has a volume of 0.4 liters and a temperature of 20 ° C, what will the volume of the balloon be after he heats it to a temperature of 35 ° C? 3)On hot days, you may have noticed that potato chip bags seem to “inflate”, even though they have not been opened. If I have a 250 mL bag at a temperature of 50 °F, and I leave it in my car which has a temperature of 100 ° F, what will the new volume of the bag be? Gas Law Problems #1 4. 1.00 L of a gas at standard temperature and pressure is compressed to 473 mL. What is the new pressure of the gas? 5. In a thermonuclear device, the pressure of 0.050 liters of gas within the bomb casing reaches 4.0 x 10 6 atm. When the bomb casing is destroyed by the explosion, the gas is released into the atmosphere where it reaches a pressure of 1.00 atm. What is the volume of the gas after the explosion? 6.Synthetic diamonds can be manufactured at pressures of 6.00 x 10 4 atm. If we took 2.00 liters of gas at 1.00 atm and compressed it to a pressure of 6.00 x 10 4 atm, what would the volume of that gas be? 7.Make up your own gas law problem and solve it

3. Answer a sentence for each: Problem 8: Demo 1 What do you think will happen? What happened? Draw a picture/ sketch of what happened: What law/equation does it demonstrate? Problem 9: Demo 2: What do you think will happen? What happened? Draw a picture/ sketch of what happened: What law/equation does it demonstrate?

4. Combined Gas Law 10. If divers rise too quickly from a deep dive, they get a condition called “the bends” which is caused by the expansion of very small nitrogen bubbles in the blood due to decreased pressure. If the initial volume of the bubbles in a diver’s blood is 15 mL and the initial pressure is 12.75 atm and 290 K, what is the volume of the bubbles when the diver has surfaced to 1.00 atm pressure and 295 K? 11. A bag of Tim’s Cascade potato chips is packaged at Seattle (1.00 atm and 55 0 F ) and has a volume of 315 mL. If this bag of chips is transported to Denver (0.775 atm and 40 0 F), what will the new volume of the bag be? 12.. A Los Angeles class nuclear submarine has an internal volume of eleven million liters at a pressure of 1.250 atm and 25 0 C. If a crewman were to open one of the hatches to the outside ocean while it was underwater (pressure = 15.75 atm, Temperature = 5 0 C), what be would the new volume of the air inside the submarine?
