Specific Heat of Water = 4.186 J/g°C

Specific Heat of Ice = 2.00 J/g°C

Molar Heat of Fusion = 6030 J/mol

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

2260.4 J

7897.0 J

42,657.0 J
