14. What is the total number of kilojoules of heat needed to change 150. G of
Nadusha1986 [10]

Answer:

\boxed {\boxed {\sf 50.1 \ kJ}}

Explanation:

When water changes from ice (solid) to water (liquid), it is melting or fusion. Therefore, we can use the following formula to find energy:

q=mH_f

where <em>q</em> is the energy, <em>m </em>is the mass, and <em>Hf</em> is the heat of fusion.

1. Define Values

The mass is 150 grams. The heat of fusion for water is 334 Joules per gram.

m= 150 \ g \\H_f=334 \ J/g

2. Calculate Energy

Substitute the values into the formula.

q=150 \ g * 334 \ J/g

Multiply. Note that the grams (g) will cancel each other out and leave Joules as our units.

q=150 *334 \ J

q=50100 \ J

3. Convert Units

We found the answer in joules, but the question asks for kilojoules, so we must convert.

There are 1000 Joules in 1 kilojoule. Therefore, we can divide the joules calculated by 1000.

50100 \ J *\frac{1 \ kJ}{1000 \ J}

\frac{50100 \ kJ}{1000 \ }

50.1 \ kJ

<u>50.1 kilojoules </u>are needed to change 150 grams of ice to water.
