What is compressibility?
A measure of how much the volume of matter decreases under
pressure.
200
Why are gases easily compressed?
Because of the spaces between the particles in the gas.
300
Name 3 factors that affect gas
pressure.
Gas, volume and temparature
400
How can you raise the pressure
exerted by a contained gas?
By reducing its volume
500
If the temperature is constant, as the
pressure of the gas increases, what
happens to the volume?
The volume decreases.
100
What is Boyle’s law?
For a given mass of gas in a constant temperature, the volume of the
gas there is inversely with pressure.
200
What is the equation of the Boyle’s Law?
P1xV1= P2xV2
300
What is Charles's Law?
The volume of fix mass of gas is directly
proportional to its kelvin temperature if
the pressure is kept constant.
400
What is the equation of Charles’s law?
V1/T1=V2/T2
500
If a sample of gas occupies 6.8L at 325c,
what will its volume be at 25c if the
pressure does not change.
3.38

What does Gay-Lussac’s Law state?
The pressure of a gas is directly proportional to the kelvin
temperature if the volume remains constant.
200
What is the equation is Gay-lussac’s law?
P1/T1=P2/T2
300
What is the combined gas law?
The combined gas law allows you to do calculations for situations in which
only the amount of gas is constant.
400
What is the equation of the combined gas
law?
p1xV1/T1=p2xV2/T2

A cylinder with a moveable piston contains 198 mL of nitrogen gas at
a pressure of 1.22 atm and a temperature of 302 K.
What must the final volume be for the pressure of the gas to be 1.52
atm atm at a temperature of 370 K?
Vfinal =___?___ mL
T2P1V1 / P1T1 = V2 (370K)(1.22atm)(198mL) / (1.52atm)(302K) = V2
89.3772 / 459.04 = V2
194.704mL = V2
Answer - 195mL (Rounded up due to proper amount of significant figures)

What is the ideal gas law?
The ideal gas law is the equation of state of a hypothetical ideal
gas.
200

What is the volume of 1.00 mole of a gas at standard temperature and pressure?
22.4 L

When filling a weather balloon with gas you have to consider that the gas will
expand greatly as it rises and the pressure decreases. Let’s say you put about
10.0 moles of He gas into a balloon that can inflate to hold 5000.0L. Currently,
the balloon is not full because of the high pressure on the ground. What is the
pressure when the balloon rises to a point where the temperature is -10.0°C
and the balloon has completely filled with the gas.
73 L

You decide to go on a long hot air balloon ride, so you decide to bring some shampoo to
wash your hair with. However there is some gas inside the shampoo bottle when you
start to climb into the basket at the beginning of your journey. In fact, because you are a
good scientist you decide to constantly take measurements of your surroundings. The
shampoo bottle contains 435ml of gas, under a pressure of 1.10 atm, at a temperature of
30.0°C. When you climb high into the air the bottle starts to expand eventually
exploding and covering you and your companions with Pert Plus. Eager to explain this
phenomenon you take some measurements: the pressure, you note, has dropped to
0.734 atm and the temperature has dropped to 5.00°C. To what new volume did the gas
inside the bottle expand?
598 mL
100
What is Dalton’s law of partial pressures?
At constant volume and temperature, the total pressure exerted
by a mixture of gases is equal to the sum of the partial
pressure of the component gases.
200
What is graham’s law?
known as Graham's law of effusion, was formulated by Scottish physical chemist Thomas
Graham in 1846. Graham found experimentally that the rate of effusion of a gas is inversely
proportional to the square root of the mass of its particles.
300
What is the equation of the
graham’s law
400
What is diffusion?
Diffusion is one of several transport phenomena that occur in
nature.
500
What is effusion
effusion is the process in which individual molecules flow
through a hole without collisions between molecules.
100
What is partial pressure
Contribution each gas makes to the total pressure
200
What is gas?
One of the three states of liquid
300
What is volume?
Volume is the quantity of threedimensional space enclosed by some
closed boundary
400
What is the unit for pressure?
