Assuming that outside the vacuum chamber there is some gas or liquid, then indeed there is a force that pushes on the walls to collapse. If it doesn't collapse, that means the walls are strong enough to withstand that force: weak walls would collapse.
The mass of an evacuated chamber is the mass of the chamber. If you are asking about the mass of the volume of the evacuated chamber, then it is zero.
Yes, a black hole can collapse on itself, leading to its own destruction. This process is known as black hole evaporation, where a black hole loses mass over time through a quantum mechanical process called Hawking radiation.
It is the inverse of an explosion, the force and energy "move" to the inside of the imploding object. When a star implodes it collapses into itself, decreasing in volume.
A long stroke brake chamber can be identified by the raised inlets, embossed etching on the side of the chamber and/or a trapezoidal shaped I.D. tag indicating long stroke, and the maximum stroke allowed.
The main force that causes a star to undergo gravitational collapse and transform into a black hole is the inward pull of gravity, which becomes stronger as the star's core runs out of fuel and can no longer support itself against its own gravity. This collapse results in a dense, compact object with a gravitational pull so strong that not even light can escape, creating a black hole.
It forms a 'caldera'.
When a volcano collapses into itself at its top, it forms a large crater called a caldera. Calderas are formed when the magma chamber of a volcano empties during an eruption, causing the summit to collapse inward.
caldera
When a volcano collapses on itself a caldera is then formed.
a strong gravitational force which means that the star will collapse in on itself
It forms a 'caldera'.
The molten material that you find in the magma chamber is the magma itself.
Gravitational instability theory
it doesnt.
The mass of an evacuated chamber is the mass of the chamber. If you are asking about the mass of the volume of the evacuated chamber, then it is zero.
Not. Galaxies do not collapse in on themselves
it doesnt stop
