Which mechanical event allowed early steam engines to automate water removal from mines?

💡 Explanation

When steam inside the cylinder is cooled, condensation creates a vacuum because the volume of water is much less than the steam, causing atmospheric pressure to push the piston. Therefore, cylinder vacuum causes piston motion, rather than flywheel inertia, condenser spikes, or safety valve release, which serve other purposes in the engine's operation.
