I see, then I think the case should fall into an intermediate situation. Otherwise in a pure elastic case the sphere should inflate till the internal pressure balances the external one ## \Delta P_x = \Delta P + P_2 - P_1 ## ? Thank you for the useful link.

Ah sorry I misunderstood, I meant the pressure exerted by the external environment on the sphere does not change if the pressure / volume inside the sphere changes. The equation is useful to me: so we can say that ## P_1 \Delta V_1 = \Delta E = P_2 \Delta V_2## where ##P_1## and ##P_2## are the...

I don't know the answer, for a perfectly rigid wall is it possible to find a relationship between the 2 pressures in steady conditions?

Yes, I am looking for a solution in the simplest conditions, e.g. perfect elastic medium that doesn't increase in pressure if the sphere expands.

Hi A sphere with radius r is buried in an elastic ideal medium at pressure P1. Inside the sphere I use energy E to create a variation of pressure of dP. What variation dPx I would measure if the sphere was buried in a medium at pressure P2 using the same energy E? Is it possible to solve...

Hi, I'm a science enthusiast with more questions than answers. My background is in biology, but I like maths and physics.
