How Do ‘Liquids’ Become ‘Gases’ and Why Does It Happen?

Liquids become gases when they get hot enough, and the particles inside them start to move faster. Imagine a crowd of people in a room, if everyone starts running around, it becomes harder for them to stay close together. In the same way, heat gives energy to liquid molecules, making them spread out more until they escape as gas. It’s like when you boil water and see steam rising, that's water turning into vapor.

Examples

  1. A pot of boiling soup produces steam, that’s liquid turning into gas.
  2. When you leave a cup of hot tea out, it gradually cools because the vapor escapes slower over time.
  3. You see water droplets on the outside of a cold drink can, that's condensation, but evaporation is the opposite.
