Question 8

If it takes you 10 min. to boil an egg to perfection at sea level, how long would it take to boil an egg to your taste in the Carpathian Mountains at elevations of 8,500 ft?

Accepted Answer

A)  The boiling point of water in the Carpathian Mountains is less than 100 °C because of lower atmospheric pressure which results in reduced intermolecular forces, so it would take a longer time to boil the egg. 
B)  The boiling point of water in the Carpathian Mountains is greater than 100 °C because of lower atmospheric pressure which results in increased intermolecular forces, so it would take less time to boil the egg. 
C)  The boiling point of water is always 100 °C regardless of elevation so it would take the same amount of time to boil the egg. 
A)  The boiling point of water in the Carpathian Mountains is less than 100 °C because of lower atmospheric pressure which results in reduced intermolecular forces, so it would take a longer time to boil the egg.
