Question

if a sealed balloon is filled and kept in a deep freezer for a period of time, it will shrink in size. determine the best explanation for this outcome
a the air particles inside the balloon slow down due to lower thermal energy. as a result, fewer collisions take place per unit area and this leads to a lower pressure inside the balloon. the pressure on the outside of the balloon pushes the balloon to a smaller volume
b the air particles inside the balloon slow down due to lower thermal energy. as a result, the air particles attract to each other and take up a smaller volume. therefore, the balloon shrinks.
c the rubber latex of the balloon becomes colder and will tend shrinking and push the air particles; however, the outside pressure equals the inside pressure and equilibrium is established
d the density of the air particles increases within the balloon causing some particles to escape and of an increase in the particles and, thus, pressure outside the balloon. this compresses the balloon to a smaller

Explanation:

To determine the best reasoning for the balloon shrinking in the freezer, we analyze each option:

• Option A: When the balloon is in the freezer (lower temperature), air particles inside slow down (less kinetic energy). Fewer collisions per unit area mean lower internal pressure. External pressure (from the freezer's air) then compresses the balloon to a smaller volume. This aligns with gas laws (kinetic molecular theory) where temperature affects particle motion, pressure, and volume.
• Option B: Air particles in a gas (like in a balloon) are far apart and don't have significant attractive forces (unlike in liquids/solids) that would cause them to "attract" and take less volume. This is incorrect.
• Option C: Rubber latex getting colder doesn't "push" air particles; the main factor is gas behavior with temperature, not rubber contraction driving pressure equilibrium in this way. Incorrect.
• Option D: The balloon is sealed, so air particles can't escape. Density change here isn't due to particles escaping, and the reasoning about pressure outside increasing is flawed (freezer temperature drop doesn't increase external pressure in this context). Incorrect.

Answer:

A. The air particles inside the balloon slow down due to lower thermal energy. As a result, fewer collisions take place per unit area and this leads to a lower pressure inside the balloon. The pressure on the outside of the balloon pushes the balloon to a smaller volume
