Neon occupies a volume of 2.80 L at -35°C. What volume will it occupy at 43°C?

• 3.44 L
• 4.1 L
• 2.65 L
• 3.7 L

If the pressure in a balloon remains constant what happens to the balloon's volume as the temperature of the air increases?

• the balloon shrivels up
• balloon expands
• balloon stays the same size
• balloon shrinks

If container A is 10L and is under 5 atm of pressure and container B is 10L, but under 7 atm of pressure, what is true about the number of particles inside the containers?

• can not tell from the information
• they contain the same number of particles
• container A has less particles
• container B has less particles

If I have 4 containers with equal volume and the containers are under the pressures listed below. Which container would have the lowest temperature?
Container A: 760 torr
Container B: 1000 torr
Container C: 1500 torr
Container D: 2000 torr 

• Container A
• Container B
• Container C
• Container D

Consider the lab station with the syringe probe. When the volume of air decreased what happened to pressure?

• pressure increased due to increased kinetic energy of each gas particle
• pressure increased due to the smaller volume and more collisions with the sides of the syringe
• molecules collided less due to the pressure decreased due to smaller volume  of molecules
• pressure increased because molecules were moving faster due to the increase number of molecules

A 135 mL sample of argon had its pressure changed from 75.0 kPa to 121 kPa. What is its new volume?

• 83.7 mL
• 98.3 mL
• 76.4 mL
• 5 mL

Which graph shows the correct relationship between the volume of a gas (V) and its absolute temperature (T), when pressure is held constant?

• 
• 
• 
• 

The diagram below shows a gas with an initial pressure of 4.0 atm and a volume of 0.520L in a cylinder at a constant temperature. The gas expands inside the cylinder and pushes the piston up to a volume of 2.03L. What is the final pressure of the gas after the expansion?

• 0.72 atm

• 1.02 atm

• 2.41 atm

• 8.17 atm

As the temperature of a gas is increased, the average kinetic energy of its molecules

• Decreases

• Increases

• Remains the same

A gas occupies a volume of 0.025 L at STP. At what temperature would the gas occupy a volume of 0.035 L if the pressure is held constant?

• 195.0K

• 312.2K

• 320.5K

• 382.2K
