A sealed, inflated balloon shrinks when placed in a container of liquid nitrogen (320F/196C)\left(-320^{\circ} \mathrm{F} /-196^{\circ} \mathrm{C}\right).
A sealed balloon in liquid nitrogen

Complete the statements to explain this phenomenon.
- When the balloon is placed in the liquid nitrogen, the temperature of the gas inside the balloon \square . This means the average kinetic energy of the gas particles \square
- As a result, the gas particles inside the balloon collide with its walls
\square often, resulting in a \square pressure inside the balloon.
- This causes the volume of the balloon to \square

Solution
1
Temperature of the gas inside the balloon: When the balloon is placed in the liquid nitrogen, the temperature of the gas inside the balloon decreases. This means the average kinetic energy of the gas particles decreases
2
Frequency of collisions: As a result, the gas particles inside the balloon collide with its walls less often, resulting in a lower pressure inside the balloon
3
Volume of the balloon: This causes the volume of the balloon to decrease
Answer
When the balloon is placed in the liquid nitrogen, the temperature of the gas inside the balloon decreases. This means the average kinetic energy of the gas particles decreases. As a result, the gas particles inside the balloon collide with its walls less often, resulting in a lower pressure inside the balloon. This causes the volume of the balloon to decrease.
Key Concept
Temperature and kinetic energy relationship
Explanation
When the temperature of a gas decreases, the average kinetic energy of its particles also decreases. This leads to fewer collisions with the walls of the container, resulting in lower pressure and a decrease in volume.
