Statement I : All liquids are conductors of electricity. Statement II : Under the condition of low pressure and high voltage, liquids can be made conducting.

Statement I is false because not all liquids conduct electricity. While electrolytes (like salt solutions) and liquid metals (like mercury) are good conductors due to ions or free electrons, many liquids such as distilled water, oils, and certain organic solvents are poor conductors or insulators [t3, t9]. Statement II is true as it describes the phenomenon of dielectric breakdown. Under conditions of high voltage (electric stress), even insulating liquids can undergo breakdown, where a conductive path or 'streamer' forms, allowing current to flow [t6, t7]. While the prompt mentions low pressure, in the context of electrical discharge physics (similar to Paschen's law for gases), reducing pressure or increasing voltage can facilitate the ionization of inclusions or the liquid itself, making it conducting [t6]. Thus, Statement I is incorrect while Statement II is a valid scientific principle regarding dielectric strength.
