We see in the kitchen that lowering pressure (such as in a chamber sealer) causes liquids to boil at lower temperatures and raising the pressure (such as a pressure cooker) causes liquids to boil at a higher temperature.
Sibona ekhishini ukuthi ukwehlisa ingcindezi (efana sealer chamber) ebangela lolu ketshezi ubilise at okushisa aphansi futhi bayikhulise ingcindezi (ezifana cooker ingcindezi) ebangela lolu ketshezi ubilise ezingeni lokushisa eliphakeme.
