Answer:

18,300 J

Explanation:

In order to be able to answer this question, you must know the value of water's enthalpy of fusion,

, which is listed as

ΔH↔ = 18,300J

Now, a substance's enthalpy of fusion tells you how much heat is needed in order to convert of said substance from solid at its melting point to liquid at its melting point.

In water's case, an enthalpy of fusion equal to

333.55 J g

333.55 J

of heat.

Your ice cube has a mass of

55.0 g
