How much heat is needed to melt 1.43 grams of ice into water from -5.34 to 84.3 c?
We need to find three heat values; the heat to raise the ice to melting point, the heat to melt the ice into water, and the heat to raise the temperature of the water to 84.3°C. Thus, we need three equations.
Note: The Specific Heat Capacity (c) for liquid water is 4.18J; for ice, 2.10J
Firstly, we need to raise the ice's temperature from -5.34°C to 0°C.
Secondly, find the energy needed to melt the ice. For this equation we must find the
Lastly, find the energy needed to raise the water to 84.3°C.
Now that we have all three values, add them to find the total energy required.
