விடையைக் காட்டு & விளக்கம்

விடை: (A) Low temperature, high pressure

விளக்கம்

Gases liquefy when cooled below their critical temperature and compressed.

  • (A) சரி

    Correct: cooling slows molecules and pressure pushes them together.

  • (B) தவறு

    Wrong: low pressure keeps molecules apart.

  • (C) தவறு

    Wrong: high temperature resists liquefaction.

  • (D) தவறு

    Wrong: the opposite of what is needed.
