pressure law & charle's law

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

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

Records show that the incident of tire explosion is high during summer season.  Which of the following gives the best explanation for this observation?

• there are more travellers during summer vacation
• high temperature during summer season causes the air inside the tire to expand
• vehicles' tires are no well maintained
• there is too much air inside the tires

At constant pressure, what happens to temperature of a gas when the volume doubles?

• The temperature also doubles.
• The temperature decreases to half of its original volume.
• The temperature doesn't change.
• The temperature quadruples.

Whose law explains why our ears pop in an airplane?

• Boyle

• Charles

• Aglow

• Zampelli

What is the formula Charles' Law?

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

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

If 200 mL of a gas at 27°C is cooled to -33°C at a constant pressure, the volume will be

• 250 mL
• 204 mL
• 196 mL
• 160 mL

Volume and temperature have a ______ proportionality.

• direct
• inverse
• linear
• exponential

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
