What does it mean if an egg floats before boiling? If the egg’s shell is cracked, egg white will leak out into the boiling water.

What is the boiling point of a liquid?
The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 inches] of mercury). At sea level, water boils at 100° C (212° F).
