Gas Laws

When the temperature is constant (k) inside a balloon, if you add pressure on it, the volume will ..... 

• Decrease
• Increase
• Not Change at all
• Particles will solidify 

For example, if you increase the temperature of a gas inside a balloon, the balloon will....
[pressure is constant (k)]

• Expand (increase in volume)
• Deflate (decrease in volume)

How do you convert C to Kelvin (K)?

• C + 273

• C x 273

• C / 273

• C + 32 + 273

What properties are constant in P₁V₁ = P₂V₂?

• Pressure

• Volume

• Temperature

• # of particles

A gas that has a pressure of 2 atm and a volume of 10 L. What equation would help you find the new volume if the pressure was changed to 1 atm?

• P₁/T₁ = P₂/T₂

• P₁V₁ = P₂V₂

• V₁/n₁ = V₂/n₂

• PV = nRT

A sample of a gas has a volume of 852 mL at 298 K. Which equation would help you find the temperature necessary for the gas to have a volume of 945 mL?

• P_t = P₁ + P₂ + P₃ + ...

• P₁V₁ = P₂V₂

• V₁/T₁ = V₂/T₂

• P₁V₁/T₁ = P₂V₂/T₂

If a nitrogen gas occupies a volume of 500 ml at a pressure of 0.971atm. Which equation would help calculate the volume will the gas occupy at a pressure of 1.50 atm?

• P₁V₁ = P₂V₂

• PV = nRT

• P₁/T₁ = P₂/T₂

• V₁/n₁ = V₂/n₂

A balloon of Argon gas has a volume of 150. mL when its pressure is 0.647 atm. What will the pressure of the gas be at a volume of 98.3 mL if the temperature remains constant?

• 0.987 atm
• 1.53 atm
• 2.36 atm
• 97.1 atm

A balloon of helium gas occupies a volume of 1 L at 32°C. What volume will the gas occupy if we put it in a ice bath at a temperature of 0°C, assuming pressure remains constant? HINT: Temperature units MUST be in Kelvin!

• 0 L
• 1.11 L
• 895 mL
• 632 mL

The gas in an aerosol can has a pressure of 3.00 atm at 25°C. The warning on the can tells the user not to keep the can in a place where the temperature exceeds 100°C. How high would the gas pressure be at 100°C?

• 3.76 atm
• 2.40 atm
• 12 atm
• 0.75 atm
