Why does one egg need to be boiled in Pokhara Nepal 900 m above sea level 7 min and in Hameln Germany 9 m above sea level 4 min - Parameters Pokhara cooking gas softer water Hameln electricity?
Answer . At school I remember being very impressed when I learned that mountaineers climbing Everest couldn't make decent tea because the water never got hot enough ------…- ! Broadly speaking, the temperature at which water boils varies with the atmospheric pressure, and the atmospheric pressure varies inversely with the height above sea level. This means that water at 900 m above sea level boils at a lower temperature than water at 9 m above sea level - so your egg would take longer to cook up there! You'd need the maths to work things out more precisely, but this might be as much as you need to know? Hope it gets you started, anyway. (MORE)
