The boiling point of water is 100 ° C at an atmospheric pressure of 1 atmosphere or 100 kPa , a typical level at sea level. At higher altitudes the air pressure decreases and the boiling point increases. Study the graph and the table above. Use the information to calculate the percentage increase of the boiling point from the summit of Everest to the top of the Burj Khalifa.

The boiling point of water at Mount Everest = 72 ° C The boiling point of water at Burj Khalifa = 97 ° C Therefore, Change in boiling point from Everest to Burj Khalifa is 97 - 72 = 25 ° C . Percentage increase in boiling point of water = 25 72 × 100 = 34 . 7 %

The boiling point of water is 100 ° C at an atmospheric pressure of 1 atmosphere or 100 kPa , a typical level at sea level. At higher altitudes the air pressure decreases and the boiling point increases. Will it take less time to cook pasta at the top Burj Khalifa or the summit of Everest? Explain your answer. What do you except to happen to the boiling point below sea level?

The boiling point of water at Mount Everest = 72 ° C The boiling point of water at Burj Khalifa = 97 ° C As the altitude increases, the pressure decreases, or we can also say temperature decreases. Hence, it will take less time to cook pasta at the summit of Mount Everest, as the temperature of boiling water is less than Burj Khalifa. Water will boil at a temperature greater than 100 ° C below sea level, as the pressure increases.
