2. What is compressibility?
100
What is compressibility?
A measure of how much the volume of matter decreases under pressure.

3. 200 Why are gases easily compressed?
Because of the spaces between the particles in the gas.

4. 300 Name 3 factors that affect gas pressure.
Gas, volume and temparature

5. 400 How can you raise the pressure exerted by a contained gas?
By reducing its volume

6. 500
If the temperature is constant, as the pressure of the gas increases, what happens to the volume?
The volume decreases.

7. 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.

8. What is the equation of the Boyle’s Law?
200
What is the equation of the Boyle’s Law?
P1xV1= P2xV2

9. 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.

10. What is the equation of Charles’s law?
400
What is the equation of Charles’s law?
V1/T1=V2/T2

11. 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

12. What does Gay-Lussac’s Law state?
100
What does Gay-Lussac’s Law state?
The pressure of a gas is directly proportional to the kelvin temperature if the volume remains constant.

13. What is the equation is Gay-lussac’s law?
200
What is the equation is Gay-lussac’s law?
P1/T1=P2/T2

14. 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.

15. 400
What is the equation of the combined gas law?
p1xV1/T1=p2xV2/T2

16. 500
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
/ = V2
mL = V2
Answer - 195mL (Rounded up due to proper amount of significant figures)

17. 100 What is the ideal gas law?
The ideal gas law is the equation of state of a hypothetical ideal gas.

18. 200
Given the following sets of values, calculate the unknown quantity.
a) P = 1.01 atm
V = ?
n = mol
T = 25°C
0.477 L

19. 300
What is the volume of 1.00 mole of a gas at standard temperature and pressure?
22.4 L

20. and the balloon has completely filled with the gas.
400
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 L. 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

21. inside the bottle expand?
500
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

22. What is Dalton’s law of partial pressures?
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.

23. 200
What is graham’s law?
known as Graham's law of effusion, was formulated by Scottish physical chemist Thomas Graham in Graham found experimentally that the rate of effusion of a gas is inversely proportional to the square root of the mass of its particles.

24. What is the equation of the graham’s law
300
What is the equation of the graham’s law

25. 400
What is diffusion?
Diffusion is one of several transport phenomena that occur in nature.

26. 500
What is effusion
effusion is the process in which individual molecules flow through a hole without collisions between molecules.

27. What is partial pressure
100
What is partial pressure
Contribution each gas makes to the total pressure

28. 200
What is gas?
One of the three states of liquid

29. 300
What is volume?
Volume is the quantity of three-dimensional space enclosed by some closed boundary

30. What is the unit for pressure?

What is the unit for pressure?
kpa

31. What is the unit for volume?
