Does ice boil faster than water?

Despite the common myth that cold water boils faster than hot, this is actually not true! Cold water does absorb heat faster than hot water, which may be the origin of this myth. However, once cold water reaches the temperature of hot water, its heating rate slows down and it takes just as long to boil.
