**1. Homework Statement**

Is it possible to find out the increase in pressure in a balloon if I know how much pressure I apply when I squeeze it? Or, alternatively, can I find out the change in volume of the balloon if I know how much pressure I'm applying? I know the initial volume, pressure, temperature of the balloon, and I know how much pressure I apply over a certain area when I squeeze the balloon.

**3. The Attempt at a Solution**

I understand how to solve this problem when I know the change in volume that occurs as a result of my squeezing the balloon. I would simply use the PV=nRT equation. I'm not sure however, how to approach the problem when all I know is the pressure I apply when squeezing the balloon. I would think I would need to know something about the pressure inside the balloon, and perhaps it's elasticity. After all, applying pressure on a metal box containing pressurized gas won't change it's pressure, so the elasticity of the enclosure must play some role.

Thanks in advance for any help! :)
