$100 Question from H1 What 3 measurements are used to study gas behavior?
4
$100 Answer from H1 Temperature, volume and pressure
5
$200 Question from H1 What are units for each of the following? 1. temperature 2. volume 3. pressure
6
$200 Answer from H1 1. C, kelvin 2.L, ml, cm³ 3. kPa, Pa, psi
7
$300 Question from H1 What instruments are used to measure volume Temperature and pressure?
8
$300 Answer from H1 Graduated cylinder, thermometer and a pressure gauge
9
$400 Question from H1 What is different about the helium in a balloon vs. helium in a tank used to fill the balloon?
10
$400 Answer from H1 The pressure
11
$500 Question from H1 Why doesn’t a balloon deflate from the air pressure pushing on its surface?
12
$500 Answer from H1 There is higher gas pressure inside of the ball
13
$100 Question from H2 What is the formula for pressure?
14
$100 Answer from H2 P = F/A
15
$200 Question from H2 A bicycle pump makes use of what relationship?
16
$200 Answer from H2 Volume and pressure
17
$300 Question from H2 Why doesn’t a gas have a definite volume?
18
$300 Answer from H2 Gas particles are free to move apart or closer together
19
$400 Question from H2 As gas particles move closer together what happens to their volume?
20
$400 Answer from H2 It decreases
21
$500 Question from H2 Why should people check the air pressure in their tires during the winter?
22
$500 Answer from H2 Air pressure will decrease because of decreased temperatures
23
$100 Question from H3 What does constant volume mean?
24
$100 Answer from H3 The container is closed and rigid. It does not change
25
$200 Question from H3 What could cause a helium balloon to burst as it rises into the atmosphere?
26
$200 Answer from H3 Decreasing air pressure could allow the balloon To expand and pop
27
$300 Question from H3 How does a hot air balloon rise?
28
$300 Answer from H3 Heating the air causes it to become less dense than the air outside of the balloon
29
$400 Question from H3 What factor is unchanged when demonstrating Charles Law?
30
$400 Answer from H3 pressure
31
$500 Question from H3 Force of the atmosphere on a table is 124,500N, the table has a surface area of 1.5m². What is the pressure in pascals of the atmosphere on the table?
32
$500 Answer from H3 P= F/A = 124,500N/1.5m²= 83,000Pa
33
$100 Question from H4 As pressure of a gas increases what happens to its volume?
34
$100 Answer from H4 It decreases
35
$200 Question from H4 Name 4 gases.
36
$200 Answer from H4 Answers will vary
37
$300 Question from H4 The faster the particles of a gas move The more frequently they will________.
38
$300 Answer from H4 collide
39
$400 Question from H4 What causes gas pressure?
40
$400 Answer from H4 Gas particles colliding with the walls of a container
41
$500 Question from H4 The graph of Boyles Law shows that its variables(volume and pressure) have what kind of relationship?
42
$500 Answer from H4 Varies inversely
43
$100 Question from H5 Does the pressure inside of a hot air balloon Increase when temperature is raised?
44
$100 Answer from H5 No a hot air balloon has an open bottom so pressure of the gas inside remains constant
45
$200 Question from H5 What is a graph?
46
$200 Answer from H5 A diagram that shows the relationships between 2 variable
47
$300 Question from H5 The line graph for Charles Law would pass through what point?
48
$300 Answer from H5 The origin(0,0)
49
$400 Question from H5 Describe the line graphs for both Boyles Law and Charles Law.
50
$400 Answer from H5 Boyles Law: curves downward and to the right Charles Law: A straight line passing through the origin
51
$500 Question from H5 Charles Law demonstrates what type of relationship?
52
$500 Answer from H5 It is directly proportional
53
Final Jeopardy What does directly proportional mean?
54
Final Jeopardy Answer It means that 2 variables such as Temperature and volume will change in the same way
