Question

In a calorimeter, 10 g of ice melts with a heat of fusion of 334 J/g. How much heat is released?

Answer 1

Answer:

No heat is released.

Explanation:

A substance absorbs heat when it melts.

The formula for the heat absorbed is

$q = m\Delta_{\text{fus}}H$

Data:

m = 10 g

\Delta_{fus) H=\text{334 J/g}

Calculations:

$q = 10 \times 334 = \text{3340 J = 3.34 kJ}\\\text{The ice }\boxed{\textbf{absorbs 3.34 kJ}} \text{ when it melts}.$
