Q. Water boils at a lower temperature on the hills because
✅ Correct Answer: (C)
There is a decrease in air pressure on the hills
Explanation: The boiling point of water is lower at higher altitudes due to the decreased atmospheric pressure. A liquid boils when its vapour pressure exceeds the local total pressure. As the atmospheric pressure drops, the Vapour pressure increases more than the local pressure at an even lower temperature.
