WS 8-1: Properties of gasses & conversions
_____1. A bicycle tire inflates when you pump a. compressibility
air into a valve on one side.
_____ 2. The pressure inside a basketball is higher b. has mass
than the pressure outside a basketball.
_____ 3. An air mattress springs back to its c. fills container
original shape after being pressed.
______4. A balloon filled with air weighs more d. exerts pressure
than an empty balloon.
______5. The color of 2 gasses is uniform throughout e. diffuses through other gases
the bottle containing it.
If the statement is true, write “true.” If it is false, change the underlined word or words to make the statement true. Write your answer on the line provided.
______6. Although air is a mixture of several gases, it behaves like a single
gas.
______7. Air bags are used as safety devices because air cannot be
compressed.
______8. The pressure of a gas is simply a measure of the kinetic energy of
the gas particles.
______9. The volume of a gas is equal to the volume of its container.
Answer each of the following questions in the space provided.
10. What is between gas atoms or molecules?
11. Use the answer above to explain why a gasses volume does not depend on the size of the gas particles?
To do all of these gas conversions remember: 1 atm = 101325 Pa = 760 mm Hg = 14.7 lb/in2 SHOW ALL YOUR WORK
Sample: How many mm hg are 623,567pa?
1 = Start with what you’re given on top
2= In the next fraction place the unit you want to cancel on
bottom, and the unit you want to convert into on top
3 = Multiply what’s on top and what’s on bottom and divide
1. How many mm hg are 313,896 Pa?
2. If the pressure outside is 768mm Hg, how many atmospheres is it?
3. A basketball is typically inflated to 22 lb/in2 what is that pressure in mm of Hg
4. The pressure inside a propane take is 6.8 atm, what is that pressure in lb/in2
5. When the barometer reads 780mm Hg, how many pa of pressure are pushing down on you?
6. 2 atm of pressure is how many lb/in2?
7. If a tank of compressed air at 1atm is filled until 14768mm Hg of air is inside, what is the final air pressure of the tank in atm?
8. If the bottom of the ocean is exerts 600x the pressure of that seen at sea level, how many atm would you experience at the bottom of the ocean?
9. If a tire is initially inflated to 22.8 lb/in2, and then 789mm Hg are added in at the next rest stop, how many lb/in2 is the tire finally inflated to?
10. If a vile of gas contains 1 atm of O2 and 208,650 pa of N2, what is the pressure inside the tube in mm of hg?
600, 46.05, 99.96,
2354, 101, 2325
1134.41, 10399,19.4
