Solution

The correct option is C

Statement 1 is not correct but Statement 2 is correct


Statement 1 is false while Statement 2 is true. Decreasing the pressure will cause water to boil more vigorously. When atmospheric pressure is lower, it takes less energy to bring water to boiling point. Less energy means less heat, means water will boil at lower temperature at lower atmospheric pressure.
