Molar Heat of Vaporization = 40790 J/mol


You take an ice cube (mass = 18g) from the freezer (T = -10ºC) and place it on the table. Later that day, you notice a puddle of water on the table that has reached ambient room temperature (20ºC). How much heat must have been absorbed to make this happen?

Your answer:


1867.0 J
