Expert Answer:

The  process  by  which  a substance’s liquid state changes  into  the  vapour or  gaseous state  at  a constant  temperature  by  absorption  of  heat  is known as  boiling.

In case of boiling, on heating liquids, the temperature rises

  • Particles gain energy.
  • Intermolecular force of attraction decreases.
  • Intermolecular space between the molecules of liquid increases.
  • At boiling point, particles become completely free and convert into a vapours
