Answer:

[tex]Q=20.6\frac{J}{g}[/tex]

Explanation:

Hello there!

In this case, according to the equation for the calculation of the heat during a heating process:

[tex]Q=mC(T_f-T_i)[/tex]

It is possible to compute it per gram of ice by just removing m from the equation by dividing at both sides. Next we plug in the given specific heat and the final and initial temperatures to obtain:

[tex]Q=2.06\frac{J}{g\°C}[-15\°C-(-25\°C)] \\\\Q=20.6\frac{J}{g}[/tex]
