# How much heat is needed to melt 1.43 grams of ice into water from -5.34 to 84.3 c?

##### 1 Answer

#### Explanation:

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.
