What will happen to the volume of a gas if the pressure on the gas increases, with constant temperature ?
Increase
Decrease
Nothing
Explosion!
Which of the following is NOT a unit of Pressure?
mmHg
atm
kelvin
kPa
Which equation would you use to solve the following problem:
"The volume of of 300 mL of gas at 1 atm is decreased to 100 mL. What is the new pressure?"
P1V1 = P2V2
V1/T1 = V2/T2
(P1V1)/T1 = (P2V2)/T2
None of the above
Gas is in a rigid container at room temperature. What happens to pressure as temperature increases?
pressure stays the same
pressure decreases
pressure increases
Gas is in a flexible container at room temperature. What happens to pressure as volume increases?
pressure stays the same
pressure decreases
pressure increases

0.987 atm
760 atm
0.0013 atm
A sample of H2(g) and a sample of N2(g) at the same temperature and pressure contain the same number of molecules. Each sample must have
the same volume, but a different mass
the same mass, but a different volume
both the same volume and the same mass
neither the same volume nor the same mass
Which equation would you use to solve the following problem:
"A gas occupies 2 L of space at 0 C. What will its volume be at 100 C?"
P1V1 = P2V2
V1/T1 = V2/T2
(P1V1)/T1 = (P2V2)/T2
None of the above

101.3 atm
11,143 atm
1.09 atm
0.921 atm
____ is a direct result of collisions between gas particles and the walls of their container.
Volume
Pressure
Moles
Temperature
Which equation would you use to solve the following problem:
"A gas occupies 2 L of space at 0 C and 1 atm. What will its volume be at 100 C and 2 atm?"
P1V1 = P2V2
V1/T1 = V2/T2
(P1V1)/T1 = (P2V2)/T2
None of the above
Which of the following affect the pressure a gas exerts on its container. Select ALL that apply!
Mass of the particle
Size of the particle
Volume of the container
Temperature of the gas
The number of moles of gas in the container
The pressure on a gas increases, and the volume of the gas increases. Which of the following could explain this situation?
Increased pressure always results in a volume increase because the particles spread out
The temperature of the gas also increased
The temperature of the gas decreased
None of the above; this is impossible
