A student puts air into a balloon and ties it shut. Which action listed below will lead to a decrease in pressure inside the balloon?
A) Leaving the balloon inside a car on a hot, summer day.
B) Compressing the balloon with both hands.
C) Sticking the balloon in a freezer.
D) Taking the balloon to the top of a hill.

Sticking the balloon in a freezer will cause the pressure to drop because the air inside will become colder and lead to the particles having lower kinetic energies. In, turn their rate of collisions will decrease and cause the pressure to drop. Leaving the balloon in a hot car and squeezing the balloon will cause a pressure increase and taking the balloon to the top of a hill may or may not cause a pressure increase.

Answer:

C) Sticking the balloon in a freezer.

Explanation:

When we put the balloon into the freezer then due to decrease in the temperature we can find the effect on its pressure using ideal gas Law

It is given as

[tex]PV = nRT[/tex]

so here on decreasing the temperature if volume is assumed to be constant the pressure is given as

[tex]P = \frac{nR}{V} T[/tex]

so pressure will also decrease on decreasing the temperature

so correct answer will be

C) Sticking the balloon in a freezer.
