Factors Affecting Volume of a Gas

Temperature

100

The unit of temperature used in chemistry because zero degrees is the same as zero kinetic energy.

What is Kelvin?

200

The energy of motion

What is kinetic energy

300

The average kinetic energy of the particles within a substance

what is temperature?

400

25 degrees Celsius is what in Kelvin?

298 K

500

A model showing how food coloring will disperse faster in hot water than cold water.

See board

Pressure

100

When air particles ________ with the walls of a container it creates pressure.

What is collide

200

Name three units of pressure

What is atmosphere, mmHg, inHg, PSI, Pascals, etc

300

A device containing mercury that is used to measure air pressure.

What is a barometer?

400

Who experiences more pressure from air, a person at sea level or a person at the top of a mountain?  Must explain why

The person at sea level experiences more pressure from air because there is more air above the person pushing down on them.  Imagine a column of air above each person, the one above the person at sea level would have many more air particles in the column.

500

Draw a model showing how the pressure of an enclosed syringe changes as the plunger is pushed, decreasing the volume inside the syringe.

Charles' Law

100

An increase in temperature will cause an _______ in volume of a gas 

increase

200

Rearrange the formula V₁/T₁ = V_2/T₂ to solve for T₁

T₁ = T₂V₁ / V₂

300

Provide a real life example of temperature affecting the volume of a gas

Hot air balloons, tires in cold weather, etc

400

The type of relationship there is between temperature and volume?

Direct Relationship

500

If a car tire has a volume of 10 L when the temperature outside is 298 K, what would be the volume of the tire if the temperature dropped to 0 C? (round answer to hundredths place)

9.16 L

Boyle's Law

100

An increase in the outside pressure will cause a(n) _________ in the volume of a gas.

decrease

200

Rearrange this formula to solve for P₂

P₁V₁=P₂V₂

P₂= P₁V₁/V₂

300

Provide a real life example of pressure affecting the volume of a gas

Bubbles from a scuba diver, a man's hand as he increases in elevation, etc

400

The type of relationship between outside pressure and the volume of a gas.

Inverse Relationship

500

A balloon with a volume of 1.2 L is in the bell jar at standard pressure.  If the pressure is decreased to 0.25 atm, what will the volume of the balloon change to?

(round answer to the tenths place)

4.8 L

Gay Lussac's Law

100

An increase in temperature will cause a(n) _________ in the pressure of a gas.

What is increase?

200

Rearrange the formula to solve for T₁

P₁/T₁ = P₂/T₂

T₁ = P₁T₂/P₂

300

What are two ways to increase the pressure of a basketball?

Add more air particles in the basketball

Increase the temperature of the gas in the basketball

400

The type of relationship between pressure and temperature.

Direct Relationship

500

A car tire is fully inflated to a pressure of 36 psi when the temperature outside is 22 C.  When the temperature outside increases to a temperature of 298 K, what would be the new pressure of air inside the tire?

(Round answer to the tenths place)

36.4 psi
