The textbook by Timberlake uses many units that are outside the International System of Units. Since I do not use these units in lectures, many of the book problems are useless. This is most prominent in the chapter on gases. Therefore, I am providing here some problems for practice.
(7 April 2005)
1. The volume of a
gas with pressure 120 kPa increases from 1.00 l to 4.00 l. What is the final pressure of
the gas, assuming constant temperature?
2. The pressure of
5.0 l of gas increases from 150 kPa to 163 kPa. What is the final volume of the gas,
assuming constant pressure?
3. The temperature
of 500 ml sample of gas increases from 150 K to 350 K. What is the final volume of the
sample of gas, if the pressure in the container is kept constant?
4. A gas contained
in a steel tank has a pressure of 150 kPa at a temperature of 320 K. What will be the gas
pressure when the temperature changes to 450 K?
5. At 570 Pa and 25
oC, a gas sample has a volume of 2270 ml. What is the final pressure (in Pa) at
a volume of 1250 ml and a temperature of 175 oC?
6. A gas sample
contains 4.0 g of CH4 and 2.0 g of He. What is the volume of the sample at STP?
[16.8]
7. A diver exhales
a bubble with a volume of 250 ml at a pressure of 240 kPa and a temperature of 15 oC.
What is the volume of the bubble when it reaches the surface, where the pressure is 100
kPa and the temperature is 27 oC? [630 ml]
8. How many moles
of neon occupy a volume of 14.3 l at STP?
9. A gas at 500 kPa
pressure was stored in a tank during the winter at 5.0 oC. During the summer
the temperature in the storage tank reached 40.0 oC. What was the pressure in
the tank then?
