What happens to a volcanoes magma chamber if the volcano becomes dormant?

When a volcano becomes dormant, the magma chamber may gradually cool and solidify as the supply of magma decreases. Over time, pressure within the chamber can drop, leading to the formation of solid rock known as igneous intrusions. Additionally, the surrounding rock may undergo changes due to reduced heat and pressure. While the volcano is dormant, it remains unstable and can potentially become active again if new magma rises into the chamber.
