Extra Practice:  As we work through our unit on the behavior of gasses, you will be required to perform many calculations.  The following websites give practice problems for each of the gas laws and will really help you prepare for the Gas Law Test at the end of the unit.  You will need a calculator to complete these problems.

Name ____________________________________________ Date ___________  Period _____

1. What is a gas?
 

2. What does the kinetic molecular theory explain?
 

3. Describe the three states of matter.
 
 
 
 
 
 
 

4.  Describe the typical motions of atoms in a solid, a liquid and a gas.
 
 

5.  The Kelvin scale is based on the concept of absolute zero.  Explain this concept.
 
 
 

6.  Read about temperature conversions and fill in the following chart.
 

              Comparison of Temperature Scales
 

 
7.  What are the boiling points of Oxygen, Nitrogen and Fluorine gas?
 
 

8.  In what state are these three elements gases at room temperature? (No link for this one, you have to think)
 

9.  Who invented the mercury barometer and what is it used to measure?
 

10.  What causes the pressure that a gas exerts on the walls of its container?
 
 

11.  Why do we not feel the weight of the atmosphere?
 

12.  Read the page “Pressure in Gases” and answer the questions at the end.  After you have answered the questions, click “show answers” and record your score.
 

13.  Use the Gas Law Simulation to find the volume of 1 mole of Helium gas when the pressure is 1.47 atm and the temperature is 287 K.
 

14.  Use the Gas Law Simulation to find the pressure when there is a total volume of 10.0 L of gas with 2 moles of helium gas and 3 moles of neon gas when the temperature is 300K.
 

15.  Use the Gas Law Simulation to find how the pressure changes when the total volume is increased to 20.0 L.
 
 

16.  What happens to the pressure of a confined gas at a constant temperature when the volume is reduced by 1/2?
 
 

17.  What happens to the volume of a gas at constant temperature when the pressure is increased?
 

18.  Use the relationship between pressure and volume simulation to see if changing the volume of the gas has a direct or inverse relationship with pressure when considered at a constant volume.   Draw each graph. (Hint:  If the graph of Pressure vs. Volume is a straight line, the relationship is directly proportional, if the graph of P vs. 1/V is a straight line, the relationship is inversely proportional.)
