Answer:
No he will not have hard boiled eggs for breakfast
Explanation:
The temperature required to boil the eggs is about 100⁰C. Unfortunately, at the height of the base camp (5,300 meters), water boils at 82⁰C.
This implies that the egg will not become cooked as at the time when the water begins to boil.
Since the eggs can only become hard boiled at 100⁰C and the temperature at which water boils at 5300 meters is less than that(82⁰C), the eggs can not become hard boiled.
