Question
What happens to the pressure inside a balloon when someone squeezes it (i.e., decreases its volume)? Explain what is happening to the gas particles.
Solution
When someone squeezes a balloon, the volume of the balloon decreases. According to Boyle's Law, which states that the pressure and volume of a gas have an inverse relationship when the temperature is held constant, the pressure inside the balloon increases when the volume decreases.
Here's what's happening at the molecular level:
-
A balloon is filled with gas, which is made up of tiny particles that are constantly moving and colliding with each other and the walls of the balloon.
-
When the balloon is squeezed, the space for these particles to move around in becomes smaller.
-
This means the particles will collide with each other and the walls of the balloon more frequently.
-
These increased collisions result in an increase in pressure inside the balloon.
So, in summary, when you squeeze a balloon and decrease its volume, the pressure inside the balloon increases due to more frequent collisions of the gas particles.

When you squeeze a balloon, it gets smaller and the air inside pushes harder against the walls. This happens because there's less room for the air to move around, so it bumps into the balloon more often, making the pressure increase
