Answer: Why do drops of water form when a steel plate is held over boiling water? … Now, when the vapor reaches the steel plate, it losses energy(heat) to the steel and condenses or cools down to form back liquid.

When we cover a glass of hot milk with a plate drops of water appear Why?

Explanation: We find droplets of water on underside of plates that is put on hot bowl of soup because when water is hot in soup, it evaporates and when it reaches the plate, it cools, condenses and form droplets of water on it.

Why do we observe water droplets under a plate that covers a vessel of hot water or milk just after boiling?

Water drops condense under a plate that has been used to cover a vessel containing milk that has just been boiled. This happens because the plate is cooler and the water vapour arising from the milk converts back to water on touching it. This is an example of condensation.

Why do we see small droplets of water when we hold a steel plate over a pan of boiling water?

When water is heated it evaporates, which means it turns into water vapor and expands. At 100℃ it boils, thus rapidly evaporating. And at boiling point, the invisible gas of steam is created. … Those drops of water are called condensation.
