Hi,

Imagine a beach ball with a volume of 1 liter, inflated to a pressure of 2 bar. At 5 bar it will burst.

How much weight needs to be applied (by a large vise) to make the beach ball burst?

Please see if you have additions or corrections on my work:

Video explaining the following equation and Boyle's Law

Equation:

pressure 1 * volume 1 = pressure 2 * volume 2

Rearrange to calculate volume 2:

(pressure 1 * volume 2) / pressure 2 = volume 2

Insert real numbers:

(2bar*1 liter) / 5 bar = 0.4 liter

The question becomes: how much weight needs to be applied to squish a beach ball from 1 liter and 2 bar to 0.4 liter and 5 bar?

Action = Reaction, so I need to determine the difference in force (in F) exerted by the beach ball in the two states?

I'm sorry, but I don't know how to do that? Could you help me?
