Now we knwo that materials tend to rapidly expand (explode) under given circumstances , like a wire subjected to sudden , rapid overcurrent or like a ball of hot flammable gas when heated or otherwise. Now I wonder what would happen if we had the ball of some heated rapidly expanding gas or mixture inside , and when it would explode ,shortly before that we would apply a pressure which is opposite to that of the ball ? How high we could go in terms of pressure and not break the material that encloses the gas inside the ball. In other words if one applies ever increasing but perfectly opposite forces and there is a material of some sort in the middle , what then is the limit after which something destructive happens to the material or whatever is in the middle or maybe there is no limit then , if the forces are pefectly opposite to one another? Now the forces would cancel out in the middle but the pressure would still be there. Also if we would put a piece of copper wire in a sealed pressurized container, would the sudden surge of amperage needed to blow that wire apart , increase if we would increase the the pressure that surrounds the wire? Just like water boiling temperature rises proportionally to water pressure.
