Answer:
The total amount of heat needed will be 
.
Explanation:
We will divide the calculation in two: First, the heat needed to melt the ice, and then the heat needed to warm the resulting liquid from 0°C to 37°C.
<em>i) </em>The fusion heat will be:
<em>ii)</em> The heat needed to warm the water from 
to 
will be:
So, the total amount needed will be the sum of these two results:
.
C.) <span>The total mass of an object can be assumed to be focused at one point, which is called its center of "Mass"
