Q101 / 270 · NDA 2016 (Phase 1) · General Ability

The temperature at which a solid melts to become a liquid at the atmospheric pressure is called its melting point. The melting point of a solid is an indication of

  • Correct answer
    A
    strength of the intermolecular forces of attraction
  • B
    strength of the intermolecular forces of repulsion
  • C
    molecular mass
  • D
    molecular size

Solution

The melting point is an important physical property of a compound. The melting point can be used to identify a substance and as an indication of its purity. The melting point of solid is defined as the temperature at which the solid exists in equilibrium with its liquid under an external pressure of one atmosphere. Melting point also depends upon the intermolecular force of attraction between the molecule.

Hence, the correct answer is option: 'A'.
