Hard-boiled eggs are made by placing eggs in boiling water until their whites and yolks solidify. Hard-boiling an egg take longer at high altitude than at sea level because the high altitude lowers the boiling point of the egg.
Hard-boiling an egg take longer at high altitude than at sea level because the high altitude lowers the boiling point of the egg. It takes longer for the water to reach 100°C.
Hard boiling egg is a chemical change because the egg cannot back into its original form.
Chemical change are those changes in which substance changes chemical composition. These changes are permanent changes.
Thus from the above conclusion we can say that Hard-boiled eggs are made by placing eggs in boiling water until their whites and yolks solidify. Hard-boiling an egg take longer at high altitude than at sea level because the high altitude lowers the boiling point of the egg.
