_____ 4. The diameter of a gas particle is much smaller than the distance between
any two particles.
_____ 7. When there is low pressure coming, we feel a little bit hotter.
_____ 9. When too much air is blown into a balloon, the air exerts pressure on the
its wall causing the balloon to explode.
_____ 10. A bubble rising from the bottom of the container increases in size because
the T on top is lower than the T below.
A. Identify the property exhibited in the following phenomenon. Use the choices
below for numbers 11-20, letters only.
D. Compression
.
6. You can see the dust particles dancing with the ray of light that
passes through a pinhole of the hole.
7. Too much air blown into the balloon causes the balloon to explode.
1. The larger the molecular weight, the slower the gas diffuses.
2. The air inside the tire must be decreased when travelling during
summer.
C. Comparison: Write.
5. 77 F 298K
8. Partial pressure of all the gases in a container and the total pressure
inside the container.
10. The pressure at 50℃ and pressure at 113 F.
III. Problem Solving: Solve the following problems and identify the gas law
applicable to solve the problem.
3. How many liters of space will 110.0 grams of carbon dioxide occupied at -23℃
and 912 torr? (C = 12, O = 16)
5. The total pressure of a gas mixture inside the container is 500kPa. If 45% of
oxygen, 30% nitrogen and the rest hydrogen (all in gaseous form) are present in
the container, determine the partial pressure of each gas.
6. Arrange the following gases in descending rates of diffusion: NH3, Cl2, CO, N2,
and water vapor.
7. The volume of a gas at -23℃ and 360 torr is 500 cc. What will be the
temperature, if the pressure is 540 torr and the volume is increased by one-half its
original volume?
8. A gas container has a total pressure of 100 kPa. If gas A exerts a pressure of
thrice that of gas C while gas B exerts a pressure of twice that of gas A, what is
the partial pressure of each gas?
9. Two porous containers are filled with hydrogen and helium respectively. Under
similar conditions, 3/5 of the hydrogen escapes in 5 hours. How long will it take
for 2/5 the helium to escape?
10. What is the molecular weight of a gas which diffuses 1/25 as fast as
hydrogen?
