1. The water vapour emerges from the hot food and goes up.
2. The plate covering the food item is in relative less temperature than the hot food.
3. Thus the more energetic molecules loose energy once they touch the cooler plate.
4. As the molecules lose heat, they lose energy and slow down.
5. They move closer to other gas molecules.
6. Finally these molecules collect together to form a liquid.
7. Condensation happens when molecules in a gas cool down.
