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

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 Combined Gas Law, pressure and volume are inversely related which means that

• When pressure increases, volume increases
• When pressure decreases, volume decreases
• When pressure increases, volume decreases
• When pressure doubles, volume triples

According to the Combined Gas 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 a gas is contained at 300 kPa and 200K. What will its volume be in L at 140 kPa and 100K?

• 4.3L
• 4.8L
• 6.2L
• 8.5L

Using Combined Gas Law, if the pressure of a gas starts out at 200kPa and increases to 600kPa, what would the initial temperature be if it ended up at 300K?

• 50K
• 200K
• 400K
• 100K

The energy of an object as it is in motion is defined as

• Kinetic Theory
• Kinetic energy
• Potential energy
• Electric energy

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.
