$200 Question from H1

What are units for each of the following?1. temperature2. volume3. pressure

$200 Answer from H1

1. C, kelvin2. L, ml, cm³3. kPa, Pa, psi

$300 Question from H1

What instruments are used to measure volumeTemperature and pressure?

$300 Answer from H1

Graduated cylinder, thermometer and apressure gauge

$400 Question from H1

What is different about the helium in a balloon vs. helium in a tank used to fill the balloon?

$400 Answer from H1

The pressure

$500 Question from H1

Why doesn’t a balloon deflate from the airpressure pushing on its surface?

$500 Answer from H1

There is higher gas pressure inside of the ball

$100 Question from H2

What is the formula for pressure?

$100 Answer from H2

P = F/A

$200 Question from H2

A bicycle pump makes use of what relationship?

$200 Answer from H2

Volume and pressure

$300 Question from H2

Why doesn’t a gas have a definite volume?

$300 Answer from H2

Gas particles are free to move apart or closer together

$400 Question from H2

As gas particles move closer together what happens to their volume?

$400 Answer from H2

It decreases

$500 Question from H2

Why should people check the air pressure in their tires during the winter?

$500 Answer from H2

Air pressure will decrease because ofdecreased temperatures

$100 Question from H3

What does constant volume mean?

$100 Answer from H3

The container is closed and rigid. It does not change

$200 Question from H3

What could cause a helium balloon to burst as it rises into the atmosphere?

$200 Answer from H3

Decreasing air pressure could allow the balloonTo expand and pop

$300 Question from H3

How does a hot air balloon rise?

$300 Answer from H3

Heating the air causes it to become less dense than the air outside of the balloon

$400 Question from H3

What factor is unchanged when demonstratingCharles Law?

$400 Answer from H3

pressure

$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?

$500 Answer from H3

P= F/A = 124,500N/1.5m²= 83,000Pa

$100 Question from H4

As pressure of a gas increases what happens to its volume?

$100 Answer from H4

It decreases

$200 Question from H4

Name 4 gases.

$200 Answer from H4

Answers will vary

$300 Question from H4

The faster the particles of a gas moveThe more frequently they will________ .

$300 Answer from H4

collide

$400 Question from H4

What causes gas pressure?

$400 Answer from H4

Gas particles colliding with the walls of a container

$500 Question from H4

The graph of Boyles Law shows that itsvariables(volume and pressure) have what kind of relationship?

$500 Answer from H4

Varies inversely

$100 Question from H5

Does the pressure inside of a hot air balloon Increase when temperature is raised?

$100 Answer from H5

No a hot air balloon has an open bottom so pressure of the gas inside remains constant

$200 Question from H5

What is a graph?

$200 Answer from H5

A diagram that shows the relationships between 2 variable

$300 Question from H5

The line graph for Charles Law would pass through what point?

$300 Answer from H5

The origin(0,0)

$400 Question from H5

Describe the line graphs for both Boyles Law and Charles Law.

$400 Answer from H5

Boyles Law: curves downward and to the rightCharles Law: A straight line passing through the origin

$500 Question from H5

Charles Law demonstrates what type of relationship?

$500 Answer from H5

It is directly proportional

Final Jeopardy

What does directly proportional mean?

Final Jeopardy Answer

It means that 2 variables such as Temperature and volume will change in the same way
