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 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

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

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
