Magma is molten or partially molten rock beneath the earth's surface. A magma chamber is a space, often beneath a volcano, where magma collects.
This is called the magma chamber.
When the magma chamber is no longer pressurised. Note, this does not mean that the magma chamber can not refill and cause another eruption later. Thus there is a difference between the termination of an eruption and a volcano becoming extinct (ceasing to have any more eruptions ever).

Magma is less dense than rock and is buoyant due to this density difference. It will seek out any weaknesses in the rock above it to reach the surface.

A Magma Chamber is a space (that can change size) at a depth below a volcano in which magma can accumulate prior to an eruption. A volcanic vent is a conduit connecting the magma chamber to the surface. It is though this that the magma flows during an eruption.
