Can you make a cup of tea on Everest?

It is possible to boil water at the summit of Mount Everest, but it takes longer than at sea level due to the lower air pressure. At sea level, water boils at 100 degrees Celsius (212 degrees Fahrenheit). However, at the summit of Everest, the boiling point of water is only about 86 degrees Celsius (187 degrees Fahrenheit) because the air pressure is so much lower. This means that it would take longer for water to reach a boil on Everest than it would at sea level.
