Behavior of Gases

Which factor can affect gas pressure?

• Temperature 
• Volume
• The Amount of Gas
• All of the answers are correct

At a constant pressure, if the temperature is increased, what happens to the volume?

• Increases

• decreases

• stays the same

Charles' Law States...

• As Pressure goes up volume goes down
• As Pressure goes up temperature goes up
• As Volume goes up temperature goes up 
• As Pressure goes down volume goes down 

Boyle's law shows the volume and pressure of a gas are always ........

• inversely proportional 
• directly proportional 

"STP" in chemistry is the abbreviation for:

• Stone Temple Pilots

• Standard Temperature and Pressure

• Scientifically Treated Petroleum

• Space Test Program

"STP" is equal to the following:

• 273 K, 1 atm

• 22 K, 1 atm

• 0 K, 273 atm

• 273 C, 760 mmHg

A gas occupies 4.98 L at 2.6 atm of pressure. What volume does it occupy at 1.8 atm pressure?

• 12.9 L
• 0.72 L
• 7.2 L
• 3.44 L

What is 50 C in Kelvin?

• 223
• 323
• 100
• 50

Tom Brady enjoys balloon animals from the carnival. He just received a balloon giraffe that has an initial temperature of 39.0°C and a volume of 1.28 L. If Gronkowski plays a trick on Tom, and puts his balloon giraffe into the freezer, what would be the new volume of the balloon if the temperature drops down to 8.0°C?
(Don’t forget about what must be done to temperatures!)

• 1.42 L
• 6.85 x 10⁴ L
• 3.78 L
• 1.15 L

If 200 mL of a gas at 27°C is cooled to -33°C at a constant pressure, the volume will be

• 250 mL
• 204 mL
• 196 mL
• 160 mL
