ou take a tied balloon and squeeze it between your hands, decreasing the volume. Explain what happens to the pressure of gas inside of the balloon and WHY.

Question

Please help me anseering this question. Thank you

Answer 1

Lets start with a discussion of what causes gas pressure.  In very simplistic terms,  gas pressure is caused by collisions between gas particles and the walls of the container.  There are two ways to alter gas pressure: change either the force or the frequency of the collisions.

 

So, if you decrease the volume of the balloon, what happens to the distance that the gas particles must travel before colliding with the wall of the container?   The distance decreases.

 

So, what happens to the frequency of the gas particle - container wall collisions?  The frequency increases.

 

So, if the frequency increases, what happens to the gas pressure?  The gas pressure also increases.
