Q. Will the boiling point of water in Delhi be the same as that of Leh? Give reasons.
Posted by: Kannankartik
A. No, the boiling point of water in Delhi and Leh is not the same. The boiling point depends on atmospheric pressure; greater the atmospheric pressure, higher the boiling point.
Since Leh is at a greater height than Delhi, it the atmospheric pressure of Leh will be less than that in Delhi. Hence, the boiling point of water in Leh will be lower than that of water in Delhi.
