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

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

What is 50 C in Kelvin?

• 223
• 323
• 100
• 50

Gas laws involve what three variables?

• Solid Liquid Gas 
• Speed Velocity Acceleration 
• Elements Compounds Mixtures 
• Pressure Temperature Volume 

According to the Charles' Law, volume and temperature are directly related. This means that

• When volume increases, temperature increases

• When volume increases, temperature decreases

• When volume double, pressure triples

• When volume doubles, volume is reduced by 1/2

If 6L of gas at 293K is compressed to 4L, what is the new temperature? 

• 195K

• 439.5K

• 0.082K

• 12.2K

4L of gas is contained at 300 kPa and 25 C. Pressure stays constant and temperature increases to 75 C. What is the new volume?

• 4.3L

• 4.8L

• 6.2L

• 8.5L

When a cold tire is inflated to a certain pressure and then is warmed up due to friction with the road, the pressure increases. This happens because the

• air molecules hit the walls of the tire less frequently
• rubber in the tires reacts with oxygen in the atmosphere
• air molecules speed up and collide with the tire walls more often
• air molecules diffuse rapidly through the walls of the tire.
