Which mechanical principle allowed early steam engines to pump water from deep mines?

💡 Explanation

When steam within a cylinder is condensed, atmospheric pressure creates a pressure differential because of the vacuum formed, pushing a piston that can pump water. Therefore atmospheric pressure differential results, rather than induction, thermoelectricity, or centrifugal force which use different energy conversion methods.
