What is pressure? |
pressure is the force per unit area |
|
|
What is air pressure? |
It is the force per unit area caused by collisions of air particles. Think of it as the weight of the air pushing down on you from above. the higher elevation you are at the lower the pressure. |
|
|
What are some units for air pressure and their respective amounts?
(Be able to convert between air pressure units using dimensional analysis.) |
1.0 atm = 760 mmHg = 760 torr = 101,325 Pascal (Pa) = 101.325 kPa |
|
|
What happens to the volume of a weather balloon that is released from sea level and rises in the atmosphere. |
As it rises, the air pressure is lower on the outside of the balloon and the volume inside the balloon increases according to Boyle's law and the inverse relationship between pressure and volume of a gas. |
|
|
What happens to the volume of a weather balloon that is brought to sea level from a higher elevation. |
As the balloon falls or descends, the air pressure is higher on the outside of the balloon and the volume inside the balloon decreases according to Boyle's law and the inverse relationship between pressure and volume of a gas. |
|
|
What is the formula to convert from Celsius to Kelvin? |
K = C + 273 |
|
|
What is the formula to convert from Kelvin to Celsius? |
C = K - 273 |
|
|
What are STP conditions? |
Standard Temperature = 0 Celsius Standard Pressure = 1 atmosphere
you can convert to any other unit as needed. |
|
|
What is the molar volume of any gas at STP? |
1 mol = 22.4 L
it doesn't matter what type of gas it is, this is true for all gasses. |
|
|
Which gas law relates the pressure and volume of a gas at a constant temperature? |
Boyle's Law |
|
|
Which gas law relates the volume and Kelvin temperature of a gas at constant pressure? |
Charles's Law |
|
|
Which gas law relates the changing volume, pressure and Kelvin temperature of a gas? |
Combined Gas Law |
|

. |
|
|
What relationship do the pressure and volume of a gas have according to Boyle's Law? |
Inverse or indirect
(that is why the slope is negative) |
|
|
What relationship do the temperature and volume of a gas have according to Charles's Law? |
Direct
(that is why the slope is positive) |

|
|
What is the value for "R" the Universal Gas Constant? |
0.0823 (L x atm) / (mol x K) |
|
|
Using the formula pictured...
What volume of water is formed if you begin with 6 L oxygen? |
. |
|
|
The test will contain problems using each of the following gas laws AT LEAST ONCE:
Boyle's Law Charles's Law Combined Gas Law Dalton's Law of Partial Pressure Ideal Gas Law Molar Volume of a Gas (Stoichiometry) |
You should review the worksheets / quizzes / labs we completed that contained problems using those laws. Sample problems will not be included in this flash card set. |
