Gas Review

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

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

• 195K
• 439.5K
• 0.082K
• 12.2K

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.

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

• the volume decreases and the balloon shrivels up or shrinks

• the volume increases and the balloon expands

• the volume stays the same and the balloon stays the same size

Each of the flasks shown above have different volumes (they are different sizes) but the temperature of each flask is the same. In which flask will the pressure be the highest?

• Flask 1

• Flask 2

• Flask 3

• Flask 4

Which equation would you use to solve the following problem:

"The volume of of 300 mL of gas at 1 atm is decreased to 100 mL. What is the new pressure?"

• P₁V₁ = P₂V₂

• V₁/T₁ = V₂/T₂

• (P₁V₁)/T₁ = (P₂V₂)/T₂

• None of the above

Which equation would you use to solve the following problem:

"A gas occupies 2 L of space at 0 C. What will its volume be at 100 C?"

• P₁V₁ = P₂V₂

• V₁/T₁ = V₂/T₂

• (P₁V₁)/T₁ = (P₂V₂)/T₂

• None of the above
