Question

Because the pressure falls, water boils at a lower temperature with increasing altitude. Consequently, cake mixes and boiled eggs, among other foods, must be cooked different lengths of time. Determine the boiling temperature of water at 1000 and 2000 m elevation on a standard day, and compare with the sea-level value

    Answer:

    1) The boiling point of water reduces by 3.28°C at 1,000 m above sea-level

    2) The boiling point of water reduces by 6.56°C at 2,000 m above sea-level

    Explanation:

    The variation of the boiling point of water with elevation is given as follows

    The boiling point reduces by 0.5°C for every 152.4 meter increase in elevation

    At sea-level, the boiling point temperature of water = 100°C

    1) At 1,000 m elevation, the boiling point temperature, T = 100 – (1,000/152.4) × 0.5 ≈ 96.72 °C

    Therefore, the boiling point of water reduces by 100° – 96.72° = 3.28°C at 1,000 m above sea-level

    2) At 2,000 m elevation, the boiling point temperature, T = 100 – (2,000/152.4) × 0.5 ≈ 93.44°C

    The boiling point of water reduces by 100° – 93.44° = 6.56°C at 2,000 m above sea-level
