Q. At which of the following places water would boil at lowest temperature?
Answer: Shimla
Notes: Shimla is the place among the options where water boils at low temperature. At higher altitudes, air pressure is lower. When atmospheric pressure is lower, such as at a higher altitude, it takes less energy to bring water to the boiling point. Less energy means less heat, which means water will boil at a lower temperature at a higher altitude.
