A liquid turning into a gas
When you heat a liquid enough to reach its boiling point, it becomes a gas. Here’s the exact process:
- As the particles in the liquid are heated, its temperature increases until it reaches its boiling point.
- This “boiling point” is the temperature at which there is enough heat energy to break the forces of attraction between the particles in a liquid.
- It’s important to note that this happens at a constant temperature.
- Once all the liquid has become a gas, the temperature increases again, as the heat energy is transferred.
