Question

We would have observed that the plate that covers the cooked food items has water droplets inside. Why? Explain.

Answer 1

1. The water vapor emerges from the hot food and goes up.
2. The plate covering the food item is at a relatively less temperature than the hot food.
3. Thus the more energetic molecules lose 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.
