Boyle's and Charles's Law

The relationship of which two variables are compared in Charles’s Law?

• pressure & volume
• volume & temperature
• temperature & pressure
• volume & moles (amount of gas)

What temperature scale must all temperature measurements be converted to?

• Celsius
• Fahrenheit
• Kelvin
• Does not matter

What is the formula Charles' Law?

• V = T
• VT = VT
• T₁ / V_{1 =} T₂ / V₂
• V₁ / T₁ = V₂ / T₂

What is the formula for Boyle's Law?

• P₁V₁=P₂V₂
• P₁V₁/P₂V₂
• P₁V₂=P₂V₁
• P₁/V₁=P₂/V₂

What is the new volume of the gas if the pressure on 350 L of oxygen at 720 mm Hg is decreased to 600 mm Hg?

• 420 L
• 29.16 L
• 4200.0 L
• 291.6 L

A gas at a volume of 4 liters is at a pressure of 2 atm. The volume is changed to 16 Liters, what must the new pressure be?

• 2 atm
• 12 atm
• 10 atm
• 0.5 atm

Which container will have a lower pressure?

• left
• right
• they both have the same pressure
• I don't know

Julian and Jimmy are playing basketball outside in 82°C weather. If they leave the ball outside and temperature drops down to 53°C, what will happen to the volume of the gas in the ball if the pressure remains constant?

• volume will remain the same
• volume will increase
• volume will decrease
• volume will double in size

For the problem below, what is the initial volume?

Edelman and Gronkowski want to play a game of beach volleyball. If the beach ball has a volume of 400 L at a temperature of 500 K, what will the temperature of the balloon be if the volume decreases to 176 L?

• 176 L

• 500 K

• 400 L

• 220 K

Tom Brady enjoys balloon animals from the carnival. He just received a balloon giraffe that has an initial temperature of 39.0°C and a volume of 1.28 L. If Gronkowski plays a trick on Tom, and puts his balloon giraffe into the freezer, what would be the new volume of the balloon if the temperature drops down to 8.0°C?
(Don’t forget about what must be done to temperatures!)

• 1.42 L
• 6.85 x 10⁴ L
• 3.78 L
• 1.15 L
