When all energy abstracts from a substance, what remains?

 When all energy is abstracted from a substance, what remains is typically the substance itself in a state where it lacks energy. In a theoretical context, if all forms of energy are completely extracted from a substance, it would be left in a state of minimal energy, often referred to as absolute zero. Absolute zero is the lowest possible temperature where nothing could be colder, and it is associated with the absence of thermal energy. In practical terms, reaching absolute zero is extremely challenging, if not impossible, as it would require removing all thermal motion from the particles of the substance.

Keep in mind that in the context of physics and thermodynamics, complete removal of all energy from a substance is more of a theoretical concept, and in practical scenarios, it may not be achievable due to various factors and limitations.
