The time required to cook a boiled egg to a particular level ofhardness can be calculated from the equation t =Aexp(15200/T) where t is time (min) and T is temperature (K).A is a constant whose value depends on the value of hardnessdesired.
a) A chef at a restaurant ( elevation= 9500ft ;Patm=535 mm Hg) asks you how long she must boil an eggto satisfy a customer (from sea level) orders a "3-minutes" boiledegg? what is your answer?
b) How long must you boil an egg to attain the same level of hardness in a place where Patm=646 mm Hg?
