To calculate the heat gain by the ice, we need to use the formula:
where:-
is the heat gain,-
is the mass of the ice,-
is the specific heat capacity of ice,-
is the change in temperature.Given:-
grams,-
J/g°C,- Initial temperature
,- Final temperature
.The change in temperature
is:
Now, plug in the values into the formula:
Therefore, the heat gain by the ice is:
So, the correct answer is:d. 101163.4 J
