Gas Laws Review

____ is a direct result of collisions between gas particles and the walls of their container.

• Volume

• Pressure

• Moles

• Temperature

What will happen to the volume of a gas if the pressure on the gas increases, with constant temperature ?

• Increase

• Decrease

• Nothing

• Explosion!

The pressure on a gas increases, and the volume of the gas increases. Which of the following could explain this situation?

• Increased pressure always results in a volume increase because the particles spread out

• The temperature of the gas also increased

• The temperature of the gas decreased

• None of the above; this is impossible

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

What is 50 C in Kelvin?

• 223
• 323
• 100

Each of the flasks shown below contain the same number of molecules at the same temperature.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:

"A gas occupies 2 L of space at 0 C and 1 atm. What will its volume be at 100 C and 2 atm?"

• P₁V₁ = P₂V₂

• V₁/T₁ = V₂/T₂

• (P₁V₁)/T₁ = (P₂V₂)/T₂

• None of the above

An ideal gas is sealed in a container at constant volume. If the temperature is increased to 4T, what would happen to the pressure?

• unchanged
• Increased to 4P
• Decreased to ¼ P
• Unable to determine without more information

If a balloon is cooled what will happen to the volume?

• Volume will increase
• Volume will decrease
• Volume will not change

Which of the following statements is true about an ideal gas at constant temperature?

• Pressure is inversely proportional to volume

• Volume is inversely proportional to temperature

• Pressure is directly proportional to volume

• Volume is directly proportional to temperature
