I appriciate all the help thank you =]
1. Which location would have the most air molecules per cubic foot?
Death Valley (below sea level)
Miami (at sea level)
Denver (above sea level)
2. Which of the following describes a liquid?
no specific volume/no specific shape
specific volume/specific shape
specific volume/no specific shape
3. Which conversion factor below would be used to change liters of oxygen gas to moles of oxygen gas?
22.4 mol gas = 1 L
22.4 L = 1 mol gas
6.02 x 1023 mol gas = 1 L
6.02 x 1023 L = 1 mol gas
4. The SI unit of pressure is torr.
True
False
5. If the temperature of a fixed mass of gas, such as helium in a balloon, is decreased while the pressure remains constant, the volume of the gas will
change in a totally unpredictable manner.
increase.
remain the same.
decrease.
change according to Bolye's Law
none of the above.
6. Which list below gives the states of matter from the least compressible to the most compressible?

7.403 atm
6.983 atm
0.750 kPa
8. A sample of gas initially occupies 6.0 cubic meters at a pressure of 1.5 atm. The pressure is then expanded to 2.0 atm. The temperature remaining constant, what is the new volume of the gas?
10 cubic meters
4.5 cubic meters
9.0 cubic meters
